Emilio Ballack, the teenage son of former Germany and Chelsea footballer Michael Ballack, has died after being crushed by a quad-bike near the family's holiday home in Portugal.
The 18-year-old was involved in the accident around 2am Thursday at the family's Villas do Mar estate, near the town of Troia which is just south of the capital, Lisbon.
Police said the teenager had been riding on an uneven piece of land when the bike rolled backwards and fell on top of him. Firefighters had to pull him free of the wreck before medics tried to revive him, but their efforts proved in vain and he was pronounced dead at the scene.
