The RNLI has released a video of two tombstoners who have risked their lives by jumping into jagged rocks in Portsmouth.
A member of the public caught people jumping from battlements at Old Portsmouth - a notorious place for tombstoning.
They were seen jumping 35ft into shallow water and jagged rocks across the seabed - a dangerous landing from a great height.
The video is part of RNLI's drowning awareness campaign, called Respect the Water, where the charity will be helping people to stay safe this summer.
Back in 2008, a man was paralysed and confined to a wheelchair when he jumped into the water from Southsea Pier in a tombstoning incident.
Tombstoning anywhere is incredibly dangerous but this footage is some of the most dangerous I’ve ever seen. These people are jumping from about 35ft into shallow water which hides jagged rocks on the sea bed. They are risking their lives, there is no doubt about it."
