Halloween threw itself on central London streets as a suspected illegal rave in a packed old building caused a bit of a local ruckus.

Party-goers, some in Halloween outfits, congregated around an eight story building in High Holborn. They had a running disagreement with police over music volume, safety and the legality of the rave.

Hundreds were at the venue when anger flared as the police asked people to leave the area, according to the Daily Mail. A few dozen riot officers from the Territorial Support Group came in and at least seven people were arrested.

A reveller and one policemen went to hospital, both with cuts. Another party person was taken into hospital to treat alcohol intoxication.

Several nearby buildings and cars were damaged and roads were closed, causing inconvenience to morning drivers. Some travellers were tourists who went to check out the event.

“There is music everywhere, trance, electro, progressive, psychedelic progressive,” one dancer told the Daily Mail. “We’re rebelling but we’re not harming anyone, we don’t cause damage.”
 
The dancing was still going on at midday on Sunday with police overseeing. One officer told the Mail: “We’re hoping people will get tired and go home.”
