The bodies of two 16-year-old boys have been recovered from Lough Enagh in Londonderry.
One teenager was taken to hospital, where he was later pronounced dead.
A second teen was located and recovered from the water after extensive searches by Foyle Search and Rescue and police divers.
He was sadly pronounced dead at the scene.
Inspector Brogan said police received a report shortly after 6.25pm on Monday (29 August) of a number of people in difficulty in the water.
One other male was taken to hospital for treatment to injuries, which are not believed to be life threatening.
Three others were also at the scene, and while they have been left shocked, are not physically injured.
“Enquiries are ongoing into this incident, but we believe, at this stage, that this was a tragic drowning incident. Our thoughts are with the families of those affected,” said Inspector Brogan.
