There's a crime alert in Ann Arbor after at least four home invasions.
Ann Arbor Police and the University of Michigan Department of Public Safety is investigating the incidents.
According to police, in all four incidents, the suspect went to off-campus student homes and entered through an unlocked door.
The incidents happened on July 2 and 3 in the 500 block of Hill Street, the 700 block of Division and the 300 block of Packard.
Police said the man entered through unlocked doors and stole cash.
Student Anthony Mufarreh, lives in the square mile where all of the incidents happened and he’s taking precautions.
"Little bit scary, trying to lock my door every time I leave and everything,” said Mufarreh.
That’s what police are asking all students and residents to do, since it’s a common occurrence for college students to leave their doors open.
"We leave our home open a lot, I have eight people who live in this house and people are going in and out all day,” said student, Sean Noone, who lives in the area the home invasions happened.
Police describe the suspect as a black man, 6’, 250 lbs, heavy set between 40-50 years old.
