A 29-year old man in Detroit was charged after buying high-grade explosives from an undercover agent. Sebastian Gregerson, who also went by the name of Abdurrahman Bin Mikaayl, had already amassed an arsenal of weapons and had talked about carrying out an attack.
Gregerson was the subject of a 16-month undercover investigation that started when someone alerted the FBI that he had in his possession grenades and bazookas. He is charged with unregistered possession of a destructive device and unlicensed receipt of explosive materials. If convicted, he faces up to 10 years in prison.
Speaking for the U.S. attorney general’s office in Detroit, Gina Balaya said she was unable to comment further on the case.
Two supporters of Gregerson, including a woman wearing a hijab, who were waiting outside the federal court, refused to make comments to the press.
The Detroit News reports that a picture posted on a Facebook account with the name of Sebastian Gregerson shows a man riding a horse carrying an Islamic State flag. The Facebook account also included a meme about shooting sprees.
According to the court record, Gregerson had purchased:
- Hundreds of rounds of ammunition for AK-47s
- Tactical gear
- Training video for AK-47s
- Commercial-grade road spikes (used to slow or disable vehicles)
- A semi-automatic rifle
- A pistol
- Grenades and grenade-launchers
- A Machete
He told undercover agents he had in his possession grenades and grenade launchers and said he wanted to buy smoke and fragmentation grenades and an anti-personnel mine (containing explosives and steel balls).
According to court records, “Gregerson discussed with (the undercover agent) his plans for a full tactical response to law enforcement if they came for him, including the use of grenades.”
