Crown Heights - Homeless man arrested for trying to rape 21-year-old woman in subway station

Cops nabbed a 23-year-old homeless man in connection with an attempted sex assault at Brooklyn’s Bedford-Nostrand Ave. subway station, officials said.

Demetrius Morales, a homeless man who hangs out near the Crown Heights station, allegedly tried to rape a 21-year-old woman exiting the station at 9:30 p.m. on March 14.

Cops say Morales offered to help the woman with her bags and then attacked her as the two ascended the stairs. He ran off when the woman screamed, officials said.

Investigators identified Morales through video surveillance taken at the Hoyt-Schermerhorn station four stops away minutes before Thursday’s attack.

Morales was charged with attempted rape, forcible touching and sexual abuse.
