Suspicious person in fatigues causes alarm on University of Michigan campus
Update: Man wearing gas mask and holding cat sign on U-M campus was 'a joke'
University of Michigan police said someone wearing fatigues, and possibly a gas mask, was seen entering Tisch Hall Thursday, but officers checked out the area and did not find the person.
Spokeswoman Diane Brown said the suspicious person was seen about noon. Police responded to the area and searched for the person, but Brown said nothing suspicious was found.
“Just to be safe, officers went through the buildings and did not locate anything suspicious,” Brown said.
The buildings around Tisch Hall were not evacuated and Brown said the area has been given the ‘all clear.’
Multiple tweets from students reported seeing a man walking around with a gas mask and a sign reading, “Love is in the air. Be prepared.” Brown could not immediately confirm those reports.
Police still are investigating the incident.
