Montreal police are urging the public to assist them in their search for a 75-year-old man missing since 8 p.m. Sunday and believed to be suicidal.

The search is made more critical by the fact that Claude Brossoit was only wearing slippers when he left the centre where he resides. Police did not say where his residence is. He pulled on a pair of brown or beige pants over his dark blue pyjamas and is also believed to be wearing a black coat with a red crest.

As of 7:30 a.m. Monday, the temperature in Montreal was minus 7 Celsius with a windchill of minus 15.

Brossoit is thin, stands five-feet-eight-inches tall and has grey hair.

Anyone with any information on his whereabouts is urged to 911 or Info-Crime Montreal at 514-393-1133.
