MINNEAPOLIS (AP) — Minneapolis Police are warning University of Minnesota students to stay alert following a series of violent robberies near campus.

Police said Monday they are investigating after reports of three separate robberies and assaults near campus over the weekend.

They say a man hit a female student in the face early Friday and took her wallet after following her on her walk home. They say three people assaulted a man early Saturday and took his jacket, wallet and keys. He might have suffered a broken nose.

Police say four people attacked the third victim Saturday night and took his wallet before fleeing.

A Minneapolis Police spokesman says the department and campus police are very active in educating the university community about crime prevention but there are many criminals and not enough police.
