MONTREAL -- Provincial police are using helicopters and drones as they scour Oka Beach for a Montreal man who has been missing since Monday.

Visitors at the beach found some personal belongings on the beach, including a cell phone, Monday and returned them to the security desk. As they handed over the belongings, the cell phone rang and it was the father of the missing 25-year-old who was worried he hadn’t heard from his son, according to Sgt. Marc Tessier.

Joss Kavena Nzongo is five feet 10 inches tall, weighing approximately 174 pounds and has brown hair and brown eyes. 

After a search nearby, police located the man’s vehicle in the parking lot but the young man was not there. Divers also searched the beach but found nothing so they will return to the water Wednesday to keep looking. 

Police are also trying to reach the person who found the man's bag and other belongings on Monday and to know where they were found. 

Anyone with information about the case is asked to contact Surete du Quebec at 1-800-659-4264 or online
