PORTLAND, Ore. — Court records show that the Oregon man who was arrested after an explosion went off inside his SUV was being tracked by the FBI for at least two weeks beforehand on suspicion that he was violating the terms of his 18-month probation.

The Oregonian/OregonLive reports that an arrest warrant was issued for 26-year-old Jason Schaefer hours before the explosion on Wednesday.

The FBI suspected Schaefer of having recently bought materials used to create bombs. The warrant was issued on grounds that he was a felon in possession of explosives.

Authorities say Schaefer led them on a brief chase before he stopped and set off a small handheld explosive device inside the SUV.

Authorities say the blast knocked the detective back and severely damaged Schaefer’s left hand. He was then arrested.
