The children were in a vehicle when it was stolen in Sylvan Lake on Thursday, local RCMP say.

They were found unharmed shortly after the vehicle was stolen around 4pm in the Reynolds Road area.

Police say the thief abandoned the vehicle in an alley and ran away.

Agents and canine units could not find them.

Anyone with information or surveillance footage from the area between 3:45 pm and 4:15 pm is asked to call police or Crime Stoppers.

The robber is believed to be approximately 5’10” tall and of medium build. At the time, he was wearing a heavy, dark-colored hooded jacket, a brown flat-brimmed baseball cap, blue jeans, and white shoes.
