Police have arrested the man they say is responsible for raping a 10-year-old girl on a rooftop in the Claremont section of the Bronx Friday.Officials say Enoch Roberts, 37, grabbed the little girl from the corner of 167th Street and College Avenue around 6 p.m., brought her to the rooftop of the apartment building and forced her to have sex with him. Police say they believe Roberts is emotionally disturbed. Neighbors say they are shaken up by the latest sexual assault. They say there is a continuing problem with sex offenders in the area. Even though Roberts is in police custody, parents say they are keeping their children extra close. Some parents say they want to see a lock installed on the door that leads to the roof stairwell. They would also like to see security cameras installed to prevent further attacks. Police say the victim is being treated at a local hospital.
