Police are looking for a man that they believe has committed three sexual assaults this month in Upper Manhattan. NY1 has newly released surveillance video of the man described as in his 30s, 5-feet-9-inches to 6-feet tall with a medium build. His latest attack came last week when he followed a 69-year-old woman into the elevator of her building at 158th Street and Riverside Drive and raped her—robbing her as well. The other two assaults took place in Hamilton Heights over the past few weeks, one also in an elevator at West 144th Street and Convent Avenue and the other in an alleyway at West 148th Street and Broadway. Police Commissioner Ray Kelly said, "I would urge women to be particularly aware and alert when they frequent 24-hour shopping locations. We've seen this in the past, where people are lurking outside and following the women from the locations." One woman told NY1, "I have pepper spray on my keychain. I think my dog will let me know before I'm aware that [an attacker's] behind me. And I have something else that I'm not supposed to carry, but I carry it. That's basically it."
