A 50-year-old woman was raped and robbed inside a Bronx building, cops said Wednesday.

The victim was on her way home when a strange man attacked her inside the building on W. 164th St. near Ogden Ave. around 7 p.m. on April 17, according to police.

The assailant sexually assaulted the woman, before snatching her gold chain and cross pendant, and nabbing $50, cops said.

The NYPD released a composite sketch of the suspect and is asking for the public’s help tracking him down. He is described as a man in his 30s, standing around 5’7″ and has a goatee. He was last seen wearing a gray New York Yankees hat.

Anyone with information is asked to call Crime Stoppers at (800) 577-TIPS. All calls will be kept confidential.
