SYLVAN LAKE, Alta. -- A young man is missing and presumed drowned after he fell into the water while riding an inner tube on a central Alberta lake.

RCMP say two males were using inner tubes on Sylvan Lake, west of Red Deer, Wednesday afternoon when a wave knocked both into the water.

One of the males was helped out by some people who were close by in a dinghy but the second person, who is in his 20s, could not be found.

A child who was in the dinghy swam to shore for help but police say no children needed to be rescued.

Mounties, aided by the RCMP helicopter and civilian boaters, started a search for the missing man.

The effort was eventually suspended due to darkness but was to continue Thursday.

Friends and family confrimed to CTV News Calgary that the missing man is Edmonton resident Palwinder Singh.
