Police divers pulled a man's body from Professor's Lake in Brampton on Monday morning, nearly 12 hours after the man slipped underwater.

Family members identified the victim as 22-year-old Satvar Singh.

It was initially believed Singh, who was with a friend at the time, fell into the lake while walking in the area. But police now believe the two men — neither of whom were strong swimmers — had intentionally gone into the lake. It's possible, police said, that the victim then wound up in deep water due to the lake's steep dropoff.

Prabjhot-Singh Bhuller was near the lake when two men came running looking for help. Bhuller said he joined the rescue effort, which included two people entering the water to try to rescue the man, but "nothing came up."

Peel Regional Police's underwater search and recovery team found the body shortly after resuming its search early Monday morning.

This is the second death at Professor's Lake this summer.

In May, a father drowned after jumping into the water to try and rescue one of his daughters who had slipped off a rock. The girl survived, but the father did not.

Police warned at the time how dangerous the lake can be outside of its roped-in areas. There are numerous signs in the area warning about the hazards of swimming in the unsupervised areas.
