Business owners in Plymouth are calling for tougher measures to stop young people from tombstoning off rocks and buildings on the Hoe.
Tombstoning is when people jump off high cliffs or piers into the sea unsupervised.
The Royal Plymouth Corinthian Yacht Club has installed chains and warning signs to try to stop young people from jumping off its roof.
