4 Surrey shootings in 2 days have police concerned

Three targetted shootings in the span of 19 hours were all connected, Surrey RCMP said.

A fourth shooting occurred a day later and police have called in the gang unit to investigate. 

“This type of activity is deeply concerning to the Surrey RCMP and the community” said Sgt. Dale Carr in a statement. "We are urging anyone with information regarding these shootings to come forward, it is imperative that you do, before someone else is seriously injured or killed”.

Two of the victims in the four shootings were taken to hospital, treated and released. Police do not know if there are other victims. 

Police heard about the first shooting early Tuesday morning when a 20-year-old man was dropped off at a Surrey hospital suffering from gunshot wounds. He was treated and released, but police were unable to ascertain where he got shot. 

Later that day, police found a car around 5:50 p.m. PT that the RCMP said " bore the evidence of being involved in a shooting."

Then an hour later, Surrey RCMP were called to a shooting where another 20-year-old was injured near 127th Street and 78 Avenue

Police were also called around 11 p.m.. to 128th Street and 76th Avenue after witnesses reports gunshots had been fired.

When police arrived on the scene, "it was apparent that all parties had departed," but they were "told by witnesses that four dark coloured vehicles were seen departing the area at a high rate of speed immediately after the sounds of gunshots." 

The latest shooting occurred Wednesday afternoon around 1:30 p.m.  Witnesses heard shots that had been fired near 132nd Street and 80th Avenue. No victim has been located yet.
