An El Sobrante elementary school has stepped up security measures after a man unrelated to any of the students obtained a pass to wander the halls last week, the school's principal said Wednesday.

The El Sobrante Christian School already has added more surveillance cameras to its campus and will increase the height of its fences after the Nov. 4 incident, Principal Scott Wells said.

On that day, according to Contra Costa Sheriff's Office spokesman Jimmy Lee, a man wandered into the school's attendance office around 12:50 p.m. and obtained the pass.

The man allegedly told the school he was an uncle of the female student, then used the student's name to obtain the pass. Both the sheriff's office and Wells said the man did not make contact with her, and Lee said he never asked to see her.

"He was never near her," Wells said, who added that the school does not believe the man knew the girl.

The student's mother, identified by KGO as Janea Faulk of San Pablo, told the station that the man who used her daughter's name was a stranger.

Wells said the school, a K-6 campus of about 180 students located on Argyle Road, held a safety meeting with parents on Monday. Two parents who attended were law enforcement employees, he said.

The school has added surveillance cameras and turned over video taken of the man over to authorities and to Faulk. The school also will try to increase the height of the fences that border it; they are waist-high now.

Wells said he thinks "the parents feel pretty good about what we're doing. ... They trust us."

Sheriff's Office deputies investigating the incident and have searched for the man without success, Lee said. The agency also has increased patrols near the school, Lee said.
