GLENDALE, Calif. (KABC) -- A 13-year-old boy became the target of a sexual assault inside a Glendale donut shop, and according to police, the help of two good Samaritans ultimately led officers to the suspect.
According to the Glendale Police Department, the boy was with his mother and brother at a donut shop in the 600 block of W. Glenoaks Blvd. on Aug. 31.
Surveillance video from inside the shop shows the mother and her two sons ordering food at the counter.
