A 15-year-old girl and a 17-year-old boy were recovered from the water at Alfred Dock, Seacombe yesterday evening after their decision to film a prank video for social media went horribly wrong.

Emergency services attended the incident at 8:30pm after the girl, who could not swim, had gone out into the water with a bottle of alcohol.

As part of the prank the boy intended to swim out to her, drink the bottle and then attempt to rescue her all while being filmed by another friend to upload to social media.

As the prank started to go wrong, the police received a call.

A spokesperson from Merseyside Police said: “We can confirm emergency services attended an incident at Alfred Dock, Seacombe on Sunday 9 May. 

“At around 8.30pm, a report was received of a concern for the safety of 15-year-old girl and a 17-year-old boy, who had got into difficulty in the water. 

“Police, the Coastguard and North West Ambulance Service attended and the teenagers were brought to safety at 8.55pm.”

The boy managed to self recover, however, police had to throw a line to the girl to recover her from the water.

Both were taken to hospital suffering effects of cold and immersion.

Posting on Facebook, the Wirral Coastguard and Rescue Team said: “Please don’t get involved in pranks for social media involving swimming and alcohol.

“For a few seconds on social media, you risk losing your life.

“Every year, the Coastguards deal with fatal incidents, where alcohol is a casual factor.”
