Bomb squad investigates grenade at Ann Arbor residence
The Michigan State Police Bomb Squad was called in to investigate reports of a grenade at a residence in the 500 block of East Ann Street Wednesday.
At around 5:30 p.m., a woman police described as college-aged walked into the Ann Arbor Police Department and said she was afraid her roommate, also described as college-aged, had a live grenade in their residence, said Sgt. Craig Flocken.
The bomb squad was called in and determined there was indeed a grenade, but that it wasn't live.
The grenade was properly disposed of by state police, Flocken said.
