Police concerned by 'tombstoning' after Skipton death
North Yorkshire Police have raised concerns that people continue to "tombstone" despite a teenager falling to his death in the county.
Joel Scott, 19, from Guiseley, Leeds fell into the River Wharfe near Skipton as he climbed up rocks in 2009.
He and a friend had been "tombstoning" - jumping from rocks into the river - when he fell about 25ft (7.6m).
North Yorkshire Police said more needed to be done to stop teenagers jumping from rocks during the summer months.
Pc Vanessa Bateston said: "It isn't a safe place to jump. You can have very deep depths and then you can also have very shallow areas with a cliff face sticking out from under the water.
"If you're lucky you'll hit the deep section but if you're unlucky you'll hit something shallow.
"We perhaps need to put some signage up here and work with the national parks to do something a bit more pro-active."
