Police marine units from Chatham-Kent and Essex OPP, and the RCMP were searching for a missing swimmer in Lake St. Clair.

They were called out to an area near Tecumseh about 5:45 Saturday Afternoon.

Several people in a boat about half a kilometer off shore decided to go swimming.

One of the people did not return to the boat.

A search and rescue operation was conducted last evening and the OPP’s Underwater Search and Recovery Unit (USRU) will attend today to continue what has now been deemed a recovery operation.

Further information will be provided as it becomes available.
