ST. PAUL (AP) — Authorities say a 55-year-old man kidnapped a 19-year-old man from a Minneapolis street, took him to his St. Paul home, and kept him chained up while repeatedly sexually assaulting him over four days.

The victim escaped Tuesday and went to a neighbor's for help. And on Wednesday, authorities charged Wilbert Glover with kidnapping and criminal sexual conduct.

Glover is being held on $1 million bail and is scheduled to make his first court appearance Monday. Online court records don't list an attorney for him. The criminal complaint says Glover injured himself in a holding cell after banging his head on a door frame.

Illinois Department of Corrections records show Glover was convicted in the 1980s of kidnapping and attempted murder. He was released from prison in 2008.
