Bottle explosive found in local parking structure
The University of Michigan Department of Public Safety and the Michigan State Police are investigating what appears to be the remnants of a of bottle explosive found at the Fletcher Parking Structure, 201 Fletcher Street, Ann Arbor.
Sgt. Gerry Steiner of the U-M Dept. of Public Safety said that what initially appeared to be the remnants of a pop bottle bomb may actually have been a firecracker that popped inside a 20 ounce bottle of pop with a cap on it.
"It had to be a small explosion because the pop bottle has small splits in it and there was no residue left around the bottle," said Steiner.
The bottle was discovered by a parking maintenance attendant on the second level of the parking structure. Steiner said the explosion could have gone off any time between 10 a.m. Dec. 20 and 10 a.m. Dec. 22.
Steiner said the bottle was run over by a vehicle and that the only damage was to the bottle itself.
The Michigan State Police are now pursuing the opinion of an explosives expert.
