Saskatchewan RCMP have arrested a suspect linked to an assault that left a boy on Birch Narrows Dene Nation seriously injured.

Christian Desjardin, 19, has been charged with one count each of aggravated assault, possession of a weapon, uttering threats and breach of a conditional sentence order.

Officers were called around 2:15 p.m. Friday with a report of a serious assault on the northwestern Saskatchewan First Nation.

Their investigation determined a male youth was assaulted by a man armed with a knife, RCMP said in a Friday news release.

The youth was taken to hospital with injuries described as serious, police said. They did not provide the age of the victim.

RCMP had asked for the public's help in finding Desjardin on Saturday before locating him.

He is scheduled to appear in court in La Loche, Sask., on Monday.
