Police believe the robber who shot two employees at a Surrey, B.C., gas station Monday night is responsible for five other armed robberies in the same area the day before.

Surrey RCMP Sgt. Roger Morrow said police are stepping up efforts to catch the suspect who has escalated his use of violence.

"Before last [Monday] night, shots were fired into a vending machine and one clerk [who] was going out to possibly pursue this individual … and it has now culminated with two people being very seriously wounded," Morrow said Tuesday.

Two employees at the Tempo gas station at 108 Avenue and Scott Road were both shot in the stomach during the robbery around 7 p.m. Monday, Morrow said.

"The 19-year-old … has undergone surgery; [he is a] great, tough young man. He has since come out of his anesthesia and has willingly spoken with our investigators. The 70-year-old man unfortunately is still in very critical condition."

Police have released two surveillance videotapes that captured a man robbing two convenience stores Sunday.

A man wearing a black hoodie and black track pants entered the stores, showed a handgun, then demanded cash from the cashiers, according to videotape.

Dave Atwal of Harvey's Market, one of the stores that was robbed, said the cashier who was on duty at the time was shaken up.

"He [the robber] just pointed the gun at his head and told him to go on the floor and lie down," Atwal said Tuesday.

"[The cashier] said you just come around and get whatever you want and he [the robber] said, 'No, you give me the money!' So he just gave him the money … and he just took off."

The suspect in all five robberies Sunday showed a handgun and demanded cash, police said.

On one occasion, one employee followed the suspect outside only to have a series of shots ring out in his direction, police said. He was not injured.

Police describe the suspect as 20 to 25 years old, 5-foot-9 to 5-foot-11, with a medium build.
