Niagara Regional Police are investigating the death of a 12-year-old North York boy at Sherkston Shores.
   
Police say he was swimming with two friends at the Quarry beach yesterday when he appeared to start struggling and then went under and didn't resurface.
   
An Underwater Search and Recovery Unit later recovered the body.
   
The boy's family has asked that his name not be released.
