WAUKESHA, WI (WTAQ) - Federal agents are helping Waukesha County authorities investigate the discovery of an improvised explosive device in a man's apartment.
The resident is a 20-year-old from Sussex, who's been in jail since last Thursday for violating a previous probation.
Charges have not been filed as the U.S. Bureau of Alcohol, Tobacco, Firearms, and Explosives helps local officers examine the evidence.
Sheriff's deputies served a warrant on the man, after getting a tip that a male apartment dweller possessed an explosive device.
WISN-TV in Milwaukee quoted a search warrant affidavit as saying the man was prepared to kill police and others, and set off explosives in his neighborhood.
