Alberta RCMP shot and wounded a man who made regular appearances on the outdoor reality show "Mantracker," after he was suspected of impaired driving.

Curtis Hallock -- a fan-favourite sidekick on "Mantracker" -- was shot in the leg and arm after police pulled over a vehicle on Thursday night in Grande Cache, about 400 kilometers west of Edmonton.

Hallock's sister Priscilla Bowen says he is currently in stable condition and awaiting surgery in a Grand Prairie hospital.

"I was terrified because the first call that I had was that he was shot by police," Bowen said. "Nobody knew where he was hit or how bad he was hit. I was shocked and very scared and the whole family was really worried for him."

Bowen says Hallock has yet to be charged by police.

"We are very grateful that he is doing well and that he is safe but we are really concerned about being shot at repeatedly by RCMP while unarmed," Bowen said.

Police said the confrontation ensued after the vehicle was pulled over. After being shot, Hallock fled, but was caught shortly after and taken to hospital.

"Mantracker" airs on the Outdoor Life Network (OLN) and features an expert tracker and his sidekick who ride horses through remote wilderness tracking two contestants.

Hallock was Mantracker's sidekick for several episodes during the second and fifth seasons.

"He is very calm. He never gets overly excited about anything. His demeanour on Mantracker is very accurate," Bowen said.

The show's website says that Hallock lived off the land surrounding Grande Cache, on the northern edge of Jasper National Park, his whole life and cares for a herd of wild horses there.

"In the seven years that we produced Mantracker … he was the number one sidekick that everyone loved and adored from all the sidekicks we had," Ihor Macijiwsky of Bonterra Productions said in a phone interview with CTV News.

The shooting is being investigated by the Alberta Serious Incident Response Team, which reviews incidents involving serious injury or death involving police officers.
