Two men have been charged with manslaughter over the death of a student involved in a "human catapult" stunt.
Mr Yankov died after being fired from a replica medieval catapult
Bulgarian teenager Kostadin Yankov was killed last November when he was thrown from a replica medieval catapult.
He should have landed in a large safety net during the event at Middlemoor Water Park, Woolavington near Bridgwater, Somerset.
But he hit the ground before he reached it, sustaining serious injuries, and died later in hospital.
The two men, 44-year-old David Aitkenhead, from Bridgwater, and 32-year-old Richard Wicks, from Burnham-on-Sea, have been bailed to appear before Sedgemoor Magistrates on July 23.
Mr Yankov, 19, was a student at Wadham College, Oxford, at the time of the accident.
