LAMPANG– A quiet neighborhood in northern Thailand became the scene of a major police raid this week when authorities shut down a massive, illegal Bitcoin mining operation. Officials from the Provincial Electricity Authority (PEA) and local law enforcement in Lampang province busted the hidden facility after neighbors reported dangerously hot, melting electrical wires.
Operating out of a rented commercial building, the suspects stole an estimated 2.9 million baht (roughly $80,000 USD) in electricity over eight months. The operation ran day and night, pulling a massive amount of power from the local grid. According to the original report by MGR Online , this raid highlights a growing problem in the region, where criminals rent properties under pretenses to set up hidden, power-hungry cryptocurrency mines.
The secret was ultimately revealed by observant neighbors. People living near the building, located on the busy Superhighway Lampang-Ngao Road, noticed something alarming. The electrical wires outside the property were getting so hot that the plastic casing was actually starting to melt. Fearing that a fire could break out at any moment, the concerned locals quickly called the Provincial Electricity Authority (PEA) to investigate the issue.
When PEA workers arrived, they discovered that the main power line was dangerously overheated. They used special thermal and electrical scanning tools to trace the intense power draw. What they found was shocking. The single commercial building was consuming as much electricity as 50 normal family homes running all at once.
However, the power meter on the front of the building looked completely normal. It was moving at a slow, standard pace. The PEA quickly realized that someone had bypassed the meter entirely, running a direct, illegal connection straight into the building from the main city grid.
- Key signs of the illegal setup:
- Melting the main electrical wires outside the building.
- Power usage equal to 50 residential homes.
- A bypassed utility meter showing normal activity.
Inside the Bitcoin Operation: Stealth and Soundproofing
Armed with a search warrant from the local provincial court, police officers from the Khelang Nakhon Police Station and PEA manager Boonyang Sangbuakaew broke into the locked property.
On the fourth floor, they uncovered the true nature of the business. The operators had set up 18 high-powered Bitcoin mining computers. These machines run complex math problems 24 hours a day to earn digital currency, creating a huge amount of heat and noise in the process.
To keep the secret hidden, the criminals did not use air conditioners, which would have drawn even more attention and power. Instead, they cleverly modified the building to create natural wind tunnels.
They knocked out specific air vents to let cross-breezes cool the machines. They also installed heavy soundproofing materials on the walls to block the loud, constant hum of the computer fans. This stealthy setup allowed them to run the mine for months without making a sound that neighbors could hear.
The Landlord’s Surprise: A Fake Business Pitch
The owner of the building had no idea what was happening inside. According to the police, the landlord had been trying to sell the empty property for a while. In September 2025, a person from Bangkok approached the owner and offered to rent two rooms.
The renter claimed they were starting a new business selling home air purifiers. The landlord agreed to a rental price of 12,000 baht per month. Trusting the tenant, the owner never visited the property to check on the “business.” When the police called the owner in the middle of the night to explain the situation, they were completely shocked to learn they had been harboring an illegal crypto mine.
The financial damage from this stolen electricity is massive. Officials estimate the stolen power alone is worth about 2.5 million baht. On top of that, the operators face a fine of at least 400,000 baht for the theft and meter tampering, bringing the total cost to nearly 3 million baht.
Beyond the stolen money, the PEA stressed that these illegal setups are incredibly dangerous. Running 50 homes’ worth of electricity through standard wires causes intense heat, creating a very real risk of a deadly electrical fire.
The PEA issued a strong warning to all landlords who rent out commercial spaces or houses:
- Check on your properties:Visit your rental spaces regularly to make sure tenants are doing what they promised on the lease.
- Look for warning signs:Unusually hot wires, weird noises, or permanently covered windows can be red flags.
- Report suspicious activity:Bypassing power meters is a serious crime that hurts the community grid and risks public safety.
If anyone suspects electricity theft, they are encouraged to contact their local PEA office or call the PEA Contact Center at 1129, available 24 hours a day.
