Pictured: Young people dice with death as they walk on roof of Northern Ireland hospital
These are the shocking images of young people dicing with death as they walk on the roof of the Royal Victoria Hospital in Belfast.
The images released by the Belfast Trust show children as young as nine jumping from roof to roof.
Security staff say it's only a matter of time before someone falls and is killed as they take the walk of death on a daily basis.
They also slide down sloping rooftops when they are icy.
CCTV captured the terrifying scenes where most recently the incidents have been occurring at the Children's Hospital where the buildings are extremely high.
The Belfast Trust have said the incidents have caused extra distress to patients.
A Belfast Trust spokewoman said: "Our concern is the comfort and wellbeing of our patients, some of whom are extremely unwell. This sort of activity adds to their distress, as well as being very unsettling for the staff who care for them.
"It is also very dangerous for those involved.
"We are constantly reviewing our security measures to keep the environment safe, but we would appeal to them to think about the impact their activities have on our patients, as well as their own safety."
The PSNI said they are aware of the young involved in action that are both "disruptive and reckless".
Sergeant Anthony Greene said: "Our neighbourhood officers work closely with the Belfast Trust on anti-social behaviour and our patrols provide additional support to the security team at The Royal Victoria Hospital site throughout the week and during weekends.
“We are aware of young people involved in actions that are both disruptive and reckless – and could end up causing upset and injury. They run the risk of also ending up with a criminal record.
“I would also appeal to parents in the area to be aware of where their children are, and what they are up to. We all have a responsibility to work together and make this part of west Belfast a safer community in which to live.”
