NORTH HOLLYWOOD (CBSLA) —  After an armed robbery at a North Hollywood marijuana dispensary where shots were fired, chaos and confusion ensued, officials said.

The LAPD mistakenly pulled over a wrong suspect vehicle. Instead of detaining the four armed robbers, they nabbed a woman, a man and their young son.

They fled with drugs and cash. No serious injuries were reported.

The guard reported that the men took off in a white Toyota Prius. Somehow, police believed they were looking for a silver Mercedes-Benz.

A car matching that description, about a block from the pot shop, was pulled over. Sky9 was overhead when the woman was pulled out of the vehicle, placed on the ground and put in handcuffs.

Moments later, a young boy was discovered in the back seat, and police put him in a cruiser. The woman, who was seen crying, a man, and the boy eventually were allowed to drive away.

Earlier, Kim had spoken to a terrified employee of the pot shop.
