One of Scotland's top public schools has condemned a video which showed ex-pupils staging a mock "chav hunt".

"Class Wars" was posted on the internet site YouTube by former students at Glenalmond College, near Perth.

The film, which showed teenagers wearing shell suits being chased by classmates dressed as aristocrats, was partly filmed on the school grounds.

Officials have described the spoof as "deeply offensive" and said it did not reflect the ethos at the school.

It began with one teenager in a baseball cap being pulled out of a river before being subjected to a simulated beating by a couple of tweed-wearing 'attackers'.

Another scene showed a shell suit wearing gang being chased through the school grounds by two young men dressed as huntsmen and on horseback.

They were shown being 'shot' as they ran across a field and one of the 'victims' was then prodded by an aristocrat as he lay on the ground.

The warden of Glenalmond College, Gordon Woods, said the film had been made by former pupils of the £23,000-a-year school.

He said: "I strongly disapprove of this video. The film, although clearly intended as satire, is immature and deeply offensive.

"We understand it was made almost two years ago and the pupils involved are no longer at Glenalmond.

"I must stress it does not reflect the ethos of Glenalmond or that of the present community of boys and girls studying here.
