Police announced Wednesday that they have arrested the "noon duty aide" who allegedly exposed himself to an eighth grade girl in an empty room at Graham Middle School earlier this month.

Mountain View resident Christopher Galbreath, 21, was called into the Police Department on Tuesday and arrested and charged with indecent exposure, which allegedly occurred Dec. 2 in a classroom at the school used for storage.

Indecent exposure is a misdemeanor, but after receiving Galbreath's consent to search his computer, detectives allegedly found child pornography, the possession of which is a felony.

"The computer has been sent off to the computer crime lab for further analysis," said police spokesperson Liz Wylie. "They'll actually scour it for other signs of child pornography."

"We are grateful for the MVPD who have actively investigated this case and have provided ongoing support for our students," said Maurice Ghysels, superintendent of the Mountain View Whisman School District. "This employee has been placed on unpaid administrative leave since the allegation was known."

Wylie said Galbreath has not been convicted for related crimes in the past and is not a registered sex offender though police believe the Dec. 2 incident may not have been his first.

"The desire to do this kind of thing doesn't just pop into your head all of a sudden," she said. "There's got to be a first somewhere along the line, but chances are (this was) not the first time."

The suspect was booked into county jail, and bail was set at $35,000. Wylie said that if Galbreath is convicted of these charges he will be registered as a sex offender.

The arrest came nearly two weeks after the initial incident because police had to obtain a warrant through the District Attorney's office.

Detectives are asking anyone who may have information on Galbreath to contact the department at (650) 903-6395.
