UPDATED: Explosive Device Found at Evanston Police Outpost

Update:

A spokesman for the U.S. Bureau of Alcohol, Tobacco, Firearms and Explosives told the Chicago Sun-Times that the man in custody is a 19-year-old who allegedly left the device and then called in the tip in order to collect a reward.

There were three police officers in the outpost at the time, and authorities said they believe the man acted alone. The device was left in a garbage can outside of the station.
