From the Walnut Creek Police Department:
During the early morning hours on 8/23/12, WCPD officers responded to a school on Buena Vista Ave. for a reported trespasser on school grounds. Officers checked the area but were unable to locate anyone. On 8/24/12, school officials reviewed security camera footage from the previous day that showed an unknown adult male confronting a juvenile student on campus. The video shows the male committing a lewd act in the presence of the juvenile before she ran away. School officials immediately notified the police department and assisted with the initial investigation.
During the investigation WCPD officers and Detectives were able to identify a suspect that lived near the school. The suspect was identified as Darryl Allen. Detectives contacted Allen near his residence and placed him under arrest for a variety of offenses (see Crime Description/Code above).
Allen was transported to the Martinez Detention Facility and is being held on $145,000 bail.
