Up to 200 teenagers from across the country trashed a family house while the parents were away after their daughter advertised the bash on the MySpace internet site, police said today.
Revellers caused £20,000 of damage to the £230,000 property in a quiet cul-de-sac on a private development in Chipchase Court, Woodstone, Houghton-le-Spring, Co Durham.
The devastated parents have now moved out of their home to have it professionally cleaned after it was left filthy with vomit and urine.
According to reports, the invitation for the Easter Monday party was posted on the popular site as a "Skins Unofficial Party" - a reference to the controversial Channel 4 series which featured scenes where a teenage get-together got out of hand.
Worried neighbours repeatedly called police as hordes of drunken yobs caused chaos from 10.30pm on the Bank Holiday to 3am on Tuesday.
The sixth former's parents returned that morning to find a trail of devastation, which police are now investigating.
It has been alleged that party-goers urinated on the mother's wedding dress and children's clothes; stole cash and jewellery; ripped light fittings from the ceiling by swinging on them; stubbed out cigarettes on the carpet; vomited throughout the house; barricaded the back door to prevent neighbours from intervening and dyed Fred Perry clothes belonging the host's brother because they "didn't like charvas" (the North East dialect for chavs).
A Durham Police spokesman said: "The girl's parents were away, she invited people around and it spiralled out of her control.
"It was a private house party and we've been told it was advertised on MySpace.
"We had a large number of complaints from neighbours and at various points we had to intervene."
Officers left the house when the party-goers turned the music down, only to be called back later when the party resumed to full effect.
On another occasion they found scores of youngsters roaming the modern estate, which until Monday's events had not seen any police activity of any note.
"There were concerns from residents that it might lead to damage, drunkenness and rowdy behaviour," the spokesman said.
Officers even provided some youngsters with the phone numbers for local taxi firms, to get them off the streets.
The force spokesman said many youngsters were not local - with two reportedly travelling from London for the bash - and had no way to get home.
He said the force made no arrests on the night but will attempt to trace all the party-goers while investigating the allegations of criminal damage.
It was understood the teenage host was lying low today, but has not been reported missing by her family. 24dash.com
