Emergency crews airlifted a teenager to safety after he plunged 25ft in a fall in the Campsie Hills.
The 15-year-old boy suffered injuries to his head and ankle in the accident at a waterfall near Crow Road car park at Lennoxtown around 6pm on Thursday.
Police and paramedics attended the scene and a Royal Navy Sea King helicopter was called out when medics were concerned the youngster may have sustained a spinal injury.
He was airlifted to the new Queen Elizabeth University Hospital in Glasgow where he received treatment for his injuries and was later released.
The area has been the scene of a number of accidents in recent years involving young people, particularly during the warm summer months.
Four years ago, a 14-year-old had a miraculous escape after he fell 40ft at the waterfall.
A day later, a 21-year-old tumbled 25ft down a hill near the Crow Road car park.
Sea King helicopters airlifted both young people to safety.
Police are warning people to be extra cautious when walking or climbing in the area.
