Three men have been arrested in connection with a violent marijuana store robbery in Vancouver 10 days ago, while a fourth female suspect remains at large.

Vancouver police says Darnel Matsui, 28, from Medicine Hat, Hosea Smith, 26, from Calgary and Cory Robert Ulmer Brown, 20, from Surrey are all in custody facing various charges including robbery with violence (firearm) and assault.

Surveillance video taken during the robbery of the Stressed and Depressed marijuana store on East 41st Avenue in Vancouver Oct. 16 shows a number of people taking a quantity of cash and drugs during the robbery.

Police did not identify the woman but released a photo of her, also taken from surveillance video. They are asking anyone with information to contact the VPD.

Two store employees were threatened with a gun and one was punched during the robbery.

The three men were taken into custody after Surrey and Delta police executed search warrants in their respective cities. Items connected to the robbery were seized at the time.

Montague said any cash recovered would be returned to the store but not the drugs, because police cannot return illegal goods.

Stressed and Depressed has been robbed three times in the last 18 months according to Montague.
