A schoolgirl who threw a party which caused devastation at her mother's house has still not returned home.

Gemma Johnson, 15, was allowed a sleepover with three friends at the house in Alberta Road, Durrington, near Worthing, on February 22.

When Julia and Robert Anscomb returned from a night at the theatre in London they found their puppy Bailey had been drugged, thousands of pounds of damage caused and expensive electrical gadgets stolen.

One guest described how the semi-detached family home was kitted out with red lights, sex toys and a ready supply of alcohol and illegal drugs.

The teenager has not returned home since.

Stepfather Mr Anscomb said: "She is still staying with her father and is being stubborn.

"I don't really know what is going to happen in the future but that is how it stands at the moment.

"We are obviously extremely upset at what happened."

Revellers claimed the party turned into a "cross between a Hell's Angels knees-up and a Roman orgy" with guests taking ecstasy, cocaine and marijuana.

Youths left graffiti "tags" in some of the bedrooms.

Drugs were found littered throughout the five-bedroom property as well as beer cans and empty bottles of spirits.

A new £600 fridge had patterns scratched into it with a knife and Mrs Anscomb's eight-year- old daughter's room was destroyed, the canopy ripped off her bed and underwear found beneath the covers.

Mrs Anscomb previously told The Argus how she lies awake at night in disgust at the thought of partying teenagers romping in her marital bed.

She said she felt violated after groups of youngsters enjoyed sex sessions at the party which damaged her £260,000 home.

She said: "I feel like moving on but I doubt I would be able to sell the house because of the reputation it has got."

A message on the social networking site Bebo attributed to Gemma said the party "went wrong but it was well good".

The message continued: "My mother thought it would teach me a lesson by putting it in the paper. All that's done is make everyone go, wow, your party made the front page'".

Riotous events like Gemma's are increasingly common and have become known as "Skins parties".

They take their name from the Channel 4 drama Skins, about appallingly behaved adolescents.
