Police are trying to track down a man accused of inappropriately touching a girl at the Rockville Memorial Library.
The assault happened Saturday, shortly before the library was scheduled to close at 6 p.m.
A press release says a man walked up to the little girl in the children's section, pulled down her pants and touched her inappropriately.
She screamed and ran to her parents, who called police.
Police tell News4 they have video of a man lingering near the children's section about 30 minutes before the alleged assault but they are not certain that man is the suspect, so they are not releasing it at this time.
