Emergency crews spent several hours searching the Otonabee River in Peterborough, Ont., on Monday evening following reports of an unaccounted for swimmer.
Around 6:45 p.m., Peterborough Fire Services launched a search of the river near Lansdowne Street and Lock 19 of the Trent-Severn Waterway after receiving reports of an individual who was unaccounted for in the water while swimming with a group of people.
Witnesses say one person was able to get to shore but another went back underneath the water.
A search of the water by emergency crews continued until it was called off just after 9 p.m. due to darkness.
The search is expected to resume Tuesday.
