Two other shootings that also happened this week appear unrelated, the force said.
Of the four related shootings, the first occurred early Tuesday morning, when police learned that a 20-year-old man was dropped off at a hospital emergency room with gunshot wounds.
On Tuesday evening, an ambulance responded to a 20-year-old man injured in another shooting. A little more than three hours after that, gunshots were reported in an area where witnesses saw four vehicles fleeing at high speed.
The following afternoon, police responded to reports that a white SUV was chasing a black Acura at high speed, with occupants in the SUV firing at the car.
RCMP Supt. Bill Fordy issued a statement addressing both the shooters and the residents of the community.
"I ask (the people involved in the shootings) to think about the safety of your family, friends and the general public," he said. "The manner that you have chosen to resolve this dispute is careless and unacceptable.
"For the citizens of Surrey, I offer you my commitment that we are working extremely hard on all of these events — not only to solve the cases that have occurred but to safeguard against any further incidents."
Police released names and photos of five men they believed were connected to the shootings, and they asked the public to come forward with any information about them.
The list included:
— Pardip Brar, 20, of Delta.
— Indervir Johal, 21, of Surrey.
— Amrit Kular, 20, of Surrey.
— Pardeep Singh, 20, of Surrey.
— Sameh Mohammed, 20, of Surrey.
RCMP said a shooting reported late Wednesday night and another early Thursday morning were unrelated to the other four.
Just before midnight, police responded to a call about a man who was shot. The victim was a 28-year-old man from neighbouring Langley and police believe the shooting was related to drugs.
At about 3:30 a.m. on Thursday, police responded to a report of shots fired at a house in Surrey. Everyone had left by the time police arrived and there were no injuries, though the Mounties say there was evidence of gunfire.
