Authorities in Massachusetts have issued a default warrant for the arrest of Nadeem Nahas, a former municipal employee accused of operating an unauthorized cryptocurrency mining facility within the structural confines of Cohasset High School. The warrant was issued by a Quincy District Court judge after Nahas failed to appear for a scheduled arraignment to face charges of fraudulent electricity use and vandalism. The case, which has drawn national attention to the intersections of public infrastructure and digital asset exploitation, involves the alleged theft of nearly $18,000 in utility services to power a clandestine array of high-performance computing hardware.
The investigation into the illegal operation began in December 2021, when the facilities director for the town of Cohasset conducted a routine inspection of the high school’s basement and utility areas. During the walkthrough, the director discovered an unusual configuration of electrical wiring and several industrial-grade computers tucked away in a remote crawl space located near the school’s boiler room. Recognizing that the equipment was not part of the school’s standard information technology infrastructure, the official alerted the Cohasset Police Department.
Upon arrival, investigators encountered a sophisticated "mining farm" consisting of 11 individual computers. These machines were designed specifically for the purpose of validating transactions on a blockchain—a process known as mining—which rewards operators with digital currency but requires immense amounts of electrical power. The police department sought assistance from the Department of Homeland Security and the Coast Guard Investigative Service to safely dismantle the operation and conduct a forensic analysis of the hardware.
Chronology of the Cohasset Mining Operation
The timeline of the alleged criminal activity spans several months of 2021, a period during which cryptocurrency valuations were experiencing significant volatility and high market interest. According to court documents and police reports, the operation was active from April 28, 2021, through December 14, 2021. During this eight-month window, the hardware ran continuously, drawing power from the school’s municipal electrical grid 24 hours a day.
Following the discovery of the equipment in mid-December, a comprehensive three-month investigation was launched to identify the individual responsible for the installation. Police eventually linked the operation to Nadeem Nahas, who served as an assistant facilities director for the town. Nahas had legitimate access to the school’s utility areas, which allowed him to bypass standard security protocols and install the energy-intensive hardware without immediate detection.
In March 2022, as the investigation intensified and evidence began to mount, Nahas resigned from his position with the town of Cohasset. It took several more months for authorities to finalize the financial audit of the stolen utilities and file formal charges. The criminal complaint was officially lodged earlier this year, but Nahas’s failure to appear for his February court date has shifted the case from a standard prosecution to an active law enforcement pursuit.
Financial and Technical Impact on Public Infrastructure
The primary charge against Nahas centers on the theft of services. An audit conducted by the town and utility providers concluded that the 11 mining rigs consumed approximately $17,492.57 worth of electricity. This figure represents a significant burden on the local school district’s budget, as the funds were diverted from educational resources to subsidize a private enterprise.

Cryptocurrency mining is notoriously energy-intensive. Hardware used for mining, often referred to as ASICs (Application-Specific Integrated Circuits) or high-end GPUs (Graphics Processing Units), generates substantial heat and requires constant cooling. By placing the rigs in a crawl space near a boiler room, the operator leveraged the school’s existing ventilation and electrical infrastructure, further compounding the risk of fire or electrical failure.
Industry experts note that $17,500 in electricity over eight months suggests a massive constant draw of power. In a typical residential setting, such a spike would be immediately flagged by utility companies. However, in a large institutional building like a high school, where power consumption fluctuates due to HVAC systems, lighting, and kitchen equipment, the incremental increase caused by 11 computers can be more easily masked—at least until a physical inspection occurs.
Global Precedents for Energy Theft in Crypto Mining
The incident in Cohasset is not an isolated phenomenon. As the "difficulty" of mining popular cryptocurrencies like Bitcoin increases, the profit margins for miners shrink, creating a powerful incentive for bad actors to seek out "free" electricity. This has led to a global crackdown on illegal mining operations that tap into public or commercial power grids.
In July 2021, authorities in Malaysia took drastic measures to deter energy theft by using a steamroller to crush over 1,000 Bitcoin mining machines. The rigs, valued at approximately $1.2 million, had been seized during raids on operations that had collectively stolen an estimated $2 million worth of electricity from the national power company, Sarawak Energy. Malaysian officials stated that the public destruction of the equipment was necessary to demonstrate the severity of the crime.
Similarly, in August 2020, Bulgarian law enforcement agents arrested two individuals in the capital city of Sofia for orchestrating a large-scale energy theft scheme. The suspects had funneled over $1.5 million in electricity to two illegal mining farms over a period of several months. These international cases highlight a growing trend where the decentralized nature of cryptocurrency provides a motive for centralized utility fraud.
Regulatory Scrutiny and Political Reaction in the United States
The Cohasset case comes at a time when U.S. lawmakers are increasingly critical of the cryptocurrency industry’s environmental and infrastructural impact. High-profile figures, including Senator Elizabeth Warren of Massachusetts and Representative Jared Huffman of California, have spearheaded efforts to force the industry into greater transparency regarding its energy consumption.
In a recent move, eight members of Congress sent a formal inquiry to the Environmental Protection Agency (EPA) and the Department of Energy (DOE). The lawmakers expressed concern that the rapid growth of crypto mining in the United States could undermine efforts to combat climate change and strain the national power grid. The letter demanded that the agencies establish mandatory disclosure requirements for mining operations, focusing on their carbon emissions and total energy usage.
Senator Warren has been particularly vocal, describing the industry as a threat to both consumers and the environment. In a public statement, she noted that "cryptomining is a double-edged sword that drains our electrical grids and pumps out massive amounts of pollution to enrich a few individuals." The incident at Cohasset High School serves as a local example for federal proponents of stricter regulation, illustrating how the search for cheap energy can lead to criminal activity within public institutions.

Broader Implications for Municipal Security
The discovery of a secret mine in a school crawl space has prompted municipal leaders across the country to re-evaluate the security of their utility infrastructures. The case highlights a vulnerability in public buildings where "dead zones"—areas such as basements, attics, and crawl spaces—may not be monitored by security cameras or regular foot patrols.
Security analysts suggest that municipalities should implement "smart" energy monitoring systems capable of detecting anomalous power draws in specific sectors of a building. In the Cohasset case, the mining rigs ran 24/7, creating a flat-line energy signature that is distinct from the variable usage patterns of a school. Had automated monitoring been in place, the $17,000 theft might have been identified months earlier.
Furthermore, the case raises questions about internal controls and the vetting of public employees who have unfettered access to sensitive infrastructure. While Nahas was a trusted member of the facilities department, his alleged actions have forced the town of Cohasset to review its internal oversight policies.
The Future of Proof-of-Work Mining
The technical nature of the Cohasset operation likely involved "Proof-of-Work" (PoW) mining, the consensus mechanism used by Bitcoin and, formerly, Ethereum. PoW requires computers to solve complex mathematical puzzles, a process that inherently consumes vast amounts of electricity. While Ethereum transitioned to a "Proof-of-Stake" (PoS) model in 2022—reducing its energy consumption by over 99%—Bitcoin and several other prominent tokens remain on PoW.
As long as PoW remains the standard for major digital assets, the incentive for energy theft will persist. The "arms race" for computing power means that only those with the lowest energy costs can remain profitable. For individuals like Nahas, the ultimate low cost is zero, achieved through the exploitation of public resources.
As of the latest reports, law enforcement agencies are continuing their search for Nadeem Nahas. The default warrant remains active, and authorities have urged anyone with information regarding his whereabouts to come forward. The hardware seized from the high school remains in police custody as evidence, serving as a silent testament to one of the most unusual cases of municipal fraud in Massachusetts history. The outcome of this case is expected to set a legal precedent for how the theft of public utilities for digital asset production is prosecuted in the United States.
