This is the carnage visited upon a Canterbury flat after it was trashed by teenagers.

The flat’s occupier had gone away for a weekend away while her daughter was left in the city.

She was supposed to be staying with a friend, but decided to throw a party.

Unknown to the 15-year-old girl, the party was advertised on a social networking website – and the results are plain to see.

Ketchup was squeezed all over the kitchen, cushions were ripped up, drawers and cabinets were rifled through – and things were stolen.
