Mountain View police arrested a student aid who they say exposed himself in a class at Graham Middle School.
A 13-year-old student says Christopher Galbreath, 21, exposed himself on the afternoon of Dec. 2 while they were in a vacant classroom.
Police say Galbreath ran off before they arrived.
Tuesday, Mountain View police issued a warrant for his arrest on one count of indecent exposure. He was arrested later that same day.
Detectives say Galbreath also faces charges of child pornography after they say they found porn on his computer.
They are now trying to see if he could be connected to other unsolved indecent exposure cases.
They say there may be other victims who have not reported a crime.
MVPD is asking anyone with information on the suspect to call 650-903-6395.
Galbreath was booked into county jail. His bail is set at $35,000.
