BitGo engineer Jameson Lopp has recently set up a $100,000 bounty for information regarding the perpetrator of a SWATting incident that occurred late last year, that could’ve had deadly consequences if “a few variables had been different.”

Back in October of last year, Lopp took to Twitter to reveal someone sent a SWAT team to his house, and told TechCrunch it “was a huge waste of public resources” as there were dozens of patrol units, a SWAT team, a fire truck, and paramedics in his neighborhood.

Dear anonymous coward who just sent dozens of cops w/ rifles to my house w/a false hostage situation report: I am not so easily intimidated. — Jameson Lopp (@lopp) October 16, 2017

Now, the engineer revealed more details about what happened that day. Per a recently published Medium blog post, Lopp was out of his house when the SWAT team was called, and only found out it was an attack on him after an officer told him to call his family so they’d leave the neighborhood to be safe.

Local news outlets managed to get a copy of the phone call the perpetrator made to call a SWAT team. In it, he claims to live at Lopp’s address and said he shot a friend with an assault rifle after an argument. After supposedly shooting his friend, the attacker claimed to be holding others hostage after rigging the property’s door with explosives.

To further get police officers on edge, the perpetrator claied to be under the influence, and asked for a $60,000 ransom, adding that if he saw any police officers “that aren’t handling a bag full of money” he was going to “shoot them on sight.” When asked to identify himself, he hung up.

After Lopp revealed the attacker’s plan didn’t work, he claims to have received a voice mail threatening him, and demanding 9 BTC. The attacker didn’t give the engineer an address to send the funds, he said:

Next time I do anything to you, trust me, it won’t involve the police. I better get 9 Bitcoin sent to me.

In response to the threats, the engineer claims to have installed 360º 4K resolution cameras in his property, to have double checked his physical security setups, and to have taken firearms out of a safe to be ready for any event.

In the post, he makes it clear he won’t tolerate threats against him or anyone he cares about. He added: “I will defend myself and my loved ones until my dying breath with every resource at my disposal.”

Per Lopp, the Durham Police Department managed to trace the calls back to a throwaway server in Texas, but eventually hit a dead end. It then turned the case to the FBI, which hasn’t updated the engineer since.

In an attempt to bring the perpetrator to justice, Lopp set up a $100,000 bounty that’s set to be paid to “the person who provides information leading to the arrest and conviction of the perpetrator who made a fraudulent report to Durham Police Department regarding my residence on October 16 2017.”

Physical crime related to bitcoin and the cryptocurrency ecosystem has been on the rise. As CryptoGlobe covered, robbers used bear spray to steal from Bitcoin ATMs in Texas earlier this year. During the same month, police in Dubai managed to recover $1.9 million in BTC that were taken from two brothers, who were attacked by a gang of 10.
