Squatters who caused uproar among their wealthy neighbours on The Bishop's Avenue when they hosted an all-night party were moved on peacefully on Friday.

Only a handful of members of the group of homeless artists, musicians, performers and healers who call themselves "the invisible expanding collective" remained at Jersey House to watch the bailiffs move in and secure the £3million derelict mansion from any further intrusion.

Its owners Sun Real Estate, a Virgin Island-based company, were alerted to the property's new occupants after national newspaper headlines about the party, which attracted 500 revellers on July 2.

The company instructed Hampstead-based solicitors Soloman, Taylor and Shaw to act on its behalf to evict the group.

Bailiffs were busy erecting chipboard barriers over the doors and windows on eviction day while pin-striped solicitor Simon Murphy barked: "Get off this property now. I want you to stop taking pictures and leave."

Meanwhile the squatters, who claim to occupy, clean and maintain empty and neglected buildings in London, have found somewhere else to live.

Group member Andy said jokingly: "With all this media attention we feel like we've become 'the obvious expanding collective'. We're now moving to another site outside the borough to join the other members who moved on a few days ago."
