Brentwood residents getting into bed were stirred Sunday night by the sound of an LAPD helicopter circling the north Barrington area. Spokesperson and Senior Lead Officer Maria Gray says it was a case of mistaken identity. Neighbors reported a possible burglary in progress when they spotted a man in the backyard of a home under renovation. Turns out, it was a private security guard hired by the homeowners to secure the site. There are two positive results, as homeowners see the result of neighbor vigilance and the quick police response. See something, say something!
