A teenage boy who was stranded in the middle of a lake in Crystal Palace Park, south London, was rescued by firefighters on Sunday.
Emergency services, including five fire engines and police, were sent to help rescue the youth, after his friends dialled 999.
He was eventually pulled to safety by a firefighter who gave him a piggyback through the water.
Police Sergeant Lance Chenery tweeted: “A 14-year-old decided to climb across to the pontoon in the lake. He couldn’t get back – cue the emergency services.
He fell off the fireman before dry land, so he got wet anyway.”
PS Chenery had earlier tweeted: “Some rescues are hi-tech, teenager rescued by @LondonFire. Needed five fire trucks.
Assisted by @MPSBromley – this could have been avoided by the youth being sensible in the first place.”
Police said the teenager did not need medical treatment.
