EMERSON, Man. -- A man who crossed the border into Manitoba from the United States is facing several charges.

Emerson RCMP say they received a call about 1 a.m. on Saturday to assist at the port of entry at the border.

They say a 37-year-old man became aggressive while he was in cells pending the processing of his refugee claim.

It's alleged the man threatened to harm Canadian Border Services Agency officers, damaged a fire sprinkler inside his cell and physically assaulted an officer.

Ahmed Aden Ali of Minneapolis is charged with uttering threats, mischief and assaulting a peace officer.
