MILLBRAE (BCN) — A man touched a 5-year-old girl inappropriately last month in Millbrae and authorities are seeking public assistance in identifying him, San Mateo County Sheriff’s deputies said Friday.

The incident occurred in the afternoon on the week of Sept. 7-11, while the girl attended an after-school program at Lomita Park School at 200 Santa Helena Ave. in Millbrae, according to sheriff’s deputies.

It was not reported to the sheriff’s office until last week, after the child told a family friend about the incident.

Sheriff’s deputies said the girl, while attending a Mid-Peninsula Boys and Girls Club facility, was approached by a man on a school playground.

The man briefly touched the juvenile and then immediately left the vicinity, according to the sheriff’s office.

All the information authorities could provide on the suspect, based on the child’s description, was that he was a man with black hair and brown skin.

Anyone with information about the incident is asked to reach Detective Joe Cang at (650) 259-2417 or by email at jcang@smcgov.org.
