A group of schoolchildren who discovered a dead body took pictures and threw stones at the corpse.
Robert Wilshire, who is believed to have been murdered, was discovered partially submerged in a stream by a group of youngsters from a local school.
They gathered around the body and some of the children took out their mobile phones to take pictures and film the scene. Footage is believed to have been posted on the internet.
Schoolboy Connor Gallagher, 16, was one of the first on the scene close to Dorcan Technology College, Swindon, Wiltshire, a mixed secondary school with 1,200 pupils.
He told the Daily Mail: 'We were just walking past. We were just looking over and we saw a dead body.
'He was laid there. His head was just above the water and he was on his back.
'Everyone started crowding around and people had their phones out. We were telling everyone else to shut up because everyone else was trying to take pictures and laughing. Some kids were throwing stones at the body. Some kids were crying.'
A post mortem examination revealed the man, from Galsworthy Close, Swindon, had died from head injuries.
A spokesman for Wiltshire Police said that two men aged 53 and 48 were being questioned on suspicion of murder.
'A murder investigation has now begun and a major incident room has been set up at Swindon's Gablecross police station,' he said.
Callous beyond belief, or foolishness? What do you think?
