MILWAUKEE (Reuters) - The University of Wisconsin-Madison resumed activities on Wednesday evening, two hours after campus police warned students to stay indoors and shelter in place following a report of shots fired near the school.
Madison police said they had arrested two male teenagers on suspicion of robbing a 19-year-old man of his backpack, wallet and keys near campus.
Police said one of the suspects fired a round as he was being chased by a friend or friends of the victim. There were no reported injuries.
A witness told police the suspected shooter had fled into a building belonging to the Madison Area Technical College in downtown Madison. The building was searched and no suspect was found, police said.
