Police are looking for a group of people who brutally attacked a Good Samaritan when he stopped to help them with apparent car trouble in Kelowna, B.C., on Tuesday.

Robert Polyak was out driving at around 4:30 a.m. PT when he spotted three men and a woman standing around the front of a car with the hood up.

Thinking he would be doing a good deed, Polyak pulled over to help the group, which he described as "clean cut".

"I grew up in a small town as a farm boy, and when people need help, you help them. That's just the way I was raised," said Polyak.

But Polyak said what happened next has him questioning humanity.

"I was just getting out of my car, halfway out of my car and I got hit in the back of the head with a baton and hit again in the neck, in the shoulder and kicked. I just went down," said Polyak.

"It all happened within a minute. I didn't really pick up on anything that was wrong until it was too late."

Polyak said one of the men then stole his car, while the others drove off in their own car, leaving him bleeding at the side of the road. 

Fortunately, Polyak managed to call 911 and was taken to hospital, suffering a deep gash to the back of the head that took 11 staples to close.

Police later found a car matching the description of Polyak's vehicle burning on a forestry service road near Kelowna.

Polyak said despite the attack he'll continue to stop and help stranded drivers. 

"Karma will get them, I guess. It's just a horrible thing to do to somebody — especially somebody who is trying to help you."

Const. Kris Clark saud the suspects may also be responsible for stabbing a 20-year-old man overnight in the same area.

"It appears this particular person was jumped from behind, again by multiple suspects. We're investigating the possibility that these two are related and the suspects are the same," said Clark.

Clark said they are looking for three men and a woman driving a brown vehicle and are working to establish a timeline.

Police are also warning people to call RCMP if they see someone who looks like they need a helping hand.
