The Special Investigations Unit is investigating a shooting during an attempted robbery in Aurora that sent two people to hospital Thursday evening – one of them a York regional police officer.

The officer, 40, was taken to Southlake Regional Health Centre in Newmarket. His injuries do not appear to be life-threatening, police said. He was shot in the wrist.

During the course of the arrest, one of the male suspects was also shot, police said. He was taken to Sunnybrook hospital with serious injuries.

“We are trying to find exactly what the interaction was between the officer and the alleged robbery suspect that received a gunshot wound,” said Frank Phillips at SIU.

“Our people have been there most of the night, I’m sure, canvassing, looking at videos from the store, videos from the mall, looking for any independent witnesses that may have been in the area and putting our investigation together.”

Police said the shooting took place on First Commerce Dr., near Wellington St. E. and Hwy. 404 in Aurora, while the York police Hold-Up unit was making an arrest at about 8:40 p.m Thursday.

The robbery happened at the Bell store at 91 First Commerce Dr.

Three men, including a suspect who has also been shot, are in custody, York Regional Police Const. Rebecca Boyd said. Police expect to lay charges.

The incident took place in a commercial plaza, home to a number of stores and other businesses.

The K9 unit was also called to search the area for evidence, police said.
