ROSEAU, Minn. (AP) -- Authorities in northern Minnesota and Canada are urging residents to avoid contact and call police if they see a former Canadian Armed Forces reservist with alleged ties to a hate group.

Patrik Mathews has been missing for two weeks and was last seen by family members in Beausejour, northeast of Winnipeg. Canadian authorities found his truck Monday on rural property near the U.S.-Canadian border.

Authorities on both sides of the border continued searching for him Friday.

Reports say Mathews has alleged ties to a hate group. The Canadian military says its intelligence unit has been investigating Mathews for "possible racist extremist activities." Mathews requested to leave the military in April and was relieved of duty Aug. 30.

Mathews hasn't been charged with a crime.
