Los Angeles police released security video footage Thursday of three men who shot and wounded two employees during a robbery earlier this month at a Northridge marijuana dispensary.

Det. Joel Price from the West Valley station said police want help in identifying the men, who entered the medical marijuana cooperative in the 8200 block of White Oak Avenue about 9:25 p.m. Dec. 15. Two of the men fired multiple times and wounded two men before fleeing.

One of the victims took out a handgun and returned fire but was shot by the robbers, police said.

One of the victims was critically injured, having been shot several times in the head, arm and legs, police said. The other man was wounded in the back and legs.

The robbers took out what they believed was a video recorder, a small amount of marijuana and an undetermined amount of cash before leaving in a late-model Nissan Titan pickup truck.

The robbers are described as three male Latinos. Police describe one of them as between 5 feet 1 and 5 feet 10, weighing 170 pounds, with a thick mustache. He was wearing a blue and white knit ski cap with ear covers, police said.

Another was 5 feet 7 to 5 feet 10 and weighed about 170 pounds, with short brown hair, a mustache and heavy eyebrows. He was wearing a dark, hooded sweatshirt and blue jeans and also had a handgun, police said.

The third robber was described wearing dark pants, a zip-up jacket and a black New York Mets baseball cap.
