Police need help looking for a man they say robbed and raped a woman in the Bronx.

Cops say the man in this surveillance video followed a woman into the elevator of a building on East 183rd Street in University Heights Friday night.

As the door opened, they say he grabbed her from behind, assaulted her and stole her cash and two cell phones.

Investigators say he then raped her in a stairwell — before running away.

The victim was taken to a nearby hospital for treatment.

Anyone with information on the case should contact the Crime Stoppers hotline at 1-800-577-TIPS, or text CRIMES and then enter TIP577, or visit www.nypdcrimestoppers.com.
