A suspect was arrested Sunday on hate crime charges for yelling slurs at a 12-year-old boy in a Manhattan playground as he whipped the pre-teen victim with a belt, police said Sunday. Kevin Maxwell, 37, of Canarsie, Brooklyn, was charged with assault and menacing, both as hate crimes, and acting in a manner injurious to a child. Police say Maxwell confronted the victim outside the public bathroom at the Baruch Playground near Baruch Drive and E. Houston St. on the Lower East Side about 12:45 a.m. April 29. Are you stupid or something? You gay f--t, Maxwell allegedly yelled at the boy, then struck him with a belt, cops said. He and the youngster are strangers, police said. The victim suffered minor injuries. Cops put out a sketch of the suspect last month and asked the public's help identifying him. Maxwell awaits arraignment in Manhattan Criminal Court. #nydailynews #crimewatchnewyork
