Baltimore police have released another sketch (at left) of a suspected rapist in East Baltimore. Authorities are investigating a series of rapes, and have said some may be linked.

This latest picture is of an attack that occurred about 2:45 a.m. on Oct. 31 in the 400 block of N. Colvin St., near Hillen Street. Police said a 55-year-old woman was leaving a late-night church event and was making her way to a bus stop when she was approached by a man who grabbed her by the throat. He brandished a shard of glass and dragged her to an abandoned parking lot, where she was raped.

Police said this sketch is based on information from a new witness. Police had released another sketch earlier this month of a suspect in connection with the attack on Covin Street and another one that occurred at a bus stop in the 1300 block of Harford Ave. A 19-year-old woman was dragged to North Central Avenue, where a man punched her in the face repeatedly, stripped her naked and sexually assaulted her. The woman, suffering from a head injury, flagged down patrol officers.
