While conducting a search on Crown land just south of Drayton Valley, Alta., officers located a variety of stolen items valued at thousands of dollars, including a jet boat, vehicles and trailers.
As RCMP officers approached one holiday trailer, two men ran out and fled toward a nearby river.
Both men jumped into the North Saskatchewan River — one made it across and took off, while the other was swept down the river.
Mounties later arrested one man near Drayton Valley but say they're not exactly sure which of the two they've got in custody.
Sgt. Corey Kyle of the Thorsby-Breton detachment says jumping into a river is a "very dangerous way to evade police."
"While we are interested in speaking to the man who remains unaccounted, our primary focus at this time is his well-being," says Kyle. "The low temperature and fast current of the river makes it incredibly hazardous to attempt to cross."
RCMP police dogs and Air Services, along with local search and rescue teams, are currently searching riverbanks and surrounding areas.
