Police are looking for a man who attacked a girl on a southeast Houston high school campus.

Officials said a man was walking the hallways at Stephen F. Austin High School, 1700 Dumble Street, at 12:45 p.m. on Feb. 4 when he asked a female student for directions to the office. He then grabbed her around the waist and started kissing her mouth and neck, police said. The girl was able to break free briefly but was then pinned against a wall, investigators said.
