Authorities arrested a California man suspected of leaving a homemade explosive outside a police station in a small northern Colorado mountain town that failed to detonate.

FBI agents took David Michael Ansberry, 64, into custody in Chicago over the weekend, two law enforcement officials with knowledge of the investigation told The Associated Press. The officials spoke on condition of anonymity because they were not authorized to speak publicly about the case.

Very strange. "California man" build "device" in Colorado and arrested in Chicago.

Good work on the part of the Feds tracking that one down. Lots of missing details.
