38-year-old Samuel Rivera was arrested yesterday for raping a woman who was working inside a laundromat Tuesday morning. A security camera caught the brutal attack of the victim struggling and screaming after she was forced into a back room of the Second Avenue laundromat. Rivera has no previous charges of sexual assault, but has a prior conviction for dealing drugs. Cops received a tip on Friday that led them to discover Rivera in the home of relatives in the Bronx. He was also charged with second degree robbery for grabbing a handful of cash from the register. East Harlem neighbors of his seemed surprised to hear the news, telling reporters, "He lives in the neighborhood and you never know" and "He seemed very nice; I don't know what happened."
