Police are on the hunt for one shooter — or possibly more — after four people were rushed from a crowded west-end bar to hospital with gunshot wounds early Sunday morning.

A spray of bullets were fired through a window outside the nightclub, striking club-goers inside the Gingur Sky Lounge near 156 Street and 118 Avenue sometime before 2 a.m., police said.

“(A) female suffered three gunshot wounds, one into her leg and two into her back,” said Edmonton Police Staff Sgt. Robin Plomp.

Plomp says a man who was shot three times in his lower back, buttocks and leg is suffering from serious but non-life-threatening injuries. The two other victims are in hospital with non-life-threatening injuries — one was shot in the foot while the other was grazed by a bullet to the neck, police said.

The city’s public safety compliance team temporarily closed down the bar in 2008 after two violent incidents in one week.

Acting Sgt. Nicole Chapdelaine, an assistant coordinator with the city’s public safety compliance team, says the recent shooting will result in another “process” that could see the bar close down.

“We need to get all of our facts and all of the information put together in order to put forward our best case,” said Chapdelaine.

“We want to make sure we are doing a completely thorough investigation.”
