Police say a man who sexually assaulted and robbed two women earlier this month attacked a third victim Tuesday in Manhattan.

Investigators say the attack happened around 4 a.m. at West 158th Street and Riverside Drive in Hamilton Heights.

They say the man followed a 69-year-old woman into an elevator at a residential building where they say he raped and robbed her.

Police say he also attacked a woman in an alleyway at West 148th Street and Broadway on August 1.

The suspect, seen right, was caught on surveillance video entering a building on West 144th Street and Convent Avenue, where he allegedly attacked another woman on August 10.

The man is described as being in his 30s, 5-feet-9-inches to 6-feet tall with a medium build.

Anyone with information about the case is being asked to contact Crime Stoppers by calling 1-800-577-TIPS, by texting TIP577 to CRIMES, or by going to NYPDCrimeStoppers.com.
