KnockKnock Burglars, security Video

Police are looking for the so-called "Knock-Knock Burglars" in Los Angeles. The LAPD asked for tips by phone (800) 222-TIPS, text to 274637, or on LAPDOnline.org. All three black suspects are in their 20s. One knocks on the door and says it’s a food delivery. If no one answers, two male suspects break in from the back and search for valuable items. They’ve stolen jewelry, cash, and electronics in bags and pillow cases. Detectives think there are numerous similar cases committed by this crew.
