The man police sought in a series of attacks on Asian women in Manhattan last week was found dead in the basement of a Madison Avenue building, the NYPD said early Tuesday.

Tyrelle Shaw, 25, was suspected in the Chinatown attacks. Police said he acted against the women after they rejected his sexual advances.

Shaw's body was found at the bottom of the elevator shaft at 766 Madison Ave., a law-enforcement source said Monday night. The source said it appeared Shaw died of suicide.

The four attacks were considered bias incidents because the suspect complained that the Asian women wouldn't pay attention to him or submit to his sexual advances, an NYPD spokesman said.

The most recent attack was June 15, when a woman was accosted and struck on Mulberry Street near Columbus Park. The first was June 10. All victims, women between the ages of 29 and 41, were struck with a hard object in either a white or gray bag. They were treated at hospitals and released, police said.

Chinatown residents had said last week that the suspect is someone who has been recognized as hanging around the area of lower Mulberry Street by the park, a location known as "Mulberry Bend." Once notorious for its crime-ridden shantytown, the area now contains Chinese funeral homes, sandwich shops and a hotel.
