Police are looking for a man who wore an "It" clown mask when he forced a prostitute to perform oral sex on him while threatening her with a butcher knife. The 29-year-old victim met the perp, who called himself Mike, through an online escort service.

They met at 2:30 a.m. on September 20th at 34 Jefferson Avenue in Bedford-Stuyvesant. When she got to the sixth floor, she was met by Mike in an Pennywise clown mask inspired by the Stephen King novel-turned-film It.

The perp took out a butcher knife and forced the woman back into the elevator. The suspect told the victim he wouldn't kill her if she dropped to her knees and gave him oral sex, which she did. He then fled the scene; the woman waited some time before calling cops, at which point the forensic evidence in the elevator had been contaminated. Cops describe the suspect as a black male in his 20s, at least 6-foot-3 and weighing about 175 pounds.
