Chicago police Wednesday afternoon blew up a suspicious briefcase near Michigan Avenue and the Chicago River, near the heart of the downtown shopping district. One person is in custody.
Police were called to 401 N. Michigan Ave. at about 2:30 p.m. Wednesday. A man had gone to the Italian Trade Commission on the building’s 30th floor, saying that he had a meeting there. Sources say he got angry, then claimed to have a bomb in his briefcase.
