Concerns have been raised following reports of teenagers and young people jumping into water from bridges and harbours in Northumberland.
The issue has been reported at the Hagg Bank railway bridge over the River Tyne near Wylam and on the coast at Beadnell and Seaton Sluice.
It comes ahead of World Drowning Prevention Day on July 25, a UN initiative serving as an opportunity to highlight the tragic effect of drowning on families and communities.
