A 16-year-old boy was killed and a teenager was hurt when a cave roof partially collapsed in Shropshire.
Rocks and rubble fell on a group of teenagers camping at the Hermitage Caves, off Lodge Lane, Bridgnorth, overnight, West Mercia Police said.
Aiden Peter Brookes, of Bridgnorth, died in the collapse early on Monday.
An 18-year-old girl was taken to hospital with back injuries. She was described as stable and her injuries are not thought to be life-threatening.
Police said it was believed that a group of youngsters had lit a fire while camping in the sandstone cave.
A West Mercia Police spokesman said: "At this stage we are trying to establish exactly what happened but it seems that a quantity of rocks and rubble fell on those inside when part of the cave collapsed.
"It appears to be a tragic accident."
The spokesman added: "Shropshire Fire and Rescue Service dealt with a small fire inside the cave."
West Midlands Ambulance Service said the boy had gone into cardiac arrest and stopped breathing after the rock-fall.
Police said it appeared to have been a "tragic accident"
