The suspect was mowing a vacant lot on Forest Row about 2:40 p.m. Thursday when he went next door and forcibly touched the victim, who was waiting outside her home for her parents to return, police said.

The man said his name was Jose, and when the teenager ordered him to stop, he walked away, police said.
