A young boy who died after falling through a corrugated roof panel on a disused industrial building has been named as Leon Hoyle.
The 12-year-old fell through a roof in the Lune industrial estate in Lancaster, Lancashire Police said.
Officers were called at about 9.30am on Monday after the boy fell while playing with friends, the force said.
He died at the industrial estate, it said.
Detective Inspector Simon Dent, of Lancaster CID, said: "This is a tragic incident which has cost a young man his life and our thoughts are with his family and friends at this time.
"We are now investigating the circumstances surrounding the fall.
"We understand that youngsters find sites such as this interesting and want to explore them but, as this incident shows, there are potential dangers of entering abandoned buildings and we hope parents will assist us by reinforcing that message to their children, especially during the school holidays."
