Teens stopped from jumping into Douglas Bay twice this week
The coastguard is asking young people to stop swimming in the water off the southern end of Douglas Promenade.
Officers say they've had to intervene twice this week with 'numerous' teenagers jumping from the walkway into the sea.
In a separate incident last Monday, a group had to be stopped from swimming in Douglas Harbour.
But those involved have been praised as a 'credit to themselves' for listening to the advice of Coastguards and stopping what they were doing.
