According to police, the incident occurred around 4:20 p.m. on Aug. 31 when the man, who was riding a black moped, called out to the girl and exposed himself to her. The girl reportedly ignored the man and immediately told her mother.
The suspect then rode a brief distance away and walked to a nearby liquor store on Van Nuys Boulevard. That's where the girl's mother caught up to the suspect and confronted him as he left the store.
No footage of the interaction between the suspect and mother was captured, but the LAPD has released a sketch of the man. He is described as a Hispanic male of medium height and build with gray hair between 45 and 55 years old. He was seen wearing a tank top, blue jeans and a skull cap helmet.
Anyone with information on this crime is urged to call LAPD Mission Detectives at (818) 838-9975.
