RESIDENTS have talked of their horror living next to the “worst anti-social party house” ever in the city.

In a place where a terraced house will set you back £1.2m and a flat in excess of £330,000 – it has been a nightmare month for the people of Powis Square, Brighton.

A drug-laden party house - which had people climbing over neighbour’s balconies to get inside - was occupied by a 20-year-old woman.

The council believes she lost control and neighbours reported dealing of crack cocaine and knife crime.

The flat was at the centre of what a council spokesman described as"the worst and most violent cases of anti-social behaviour the council has ever experienced".

This week officers shut the flat down and boarded it up to stop further problems.

Walls leading up to the first-floor flat were still splattered with blood on Wednesday and neighbours described it as a scene from a horror movie.

One resident, who wished to remain anonymous, said: “It’s been parties, screaming coming from the flat – and it’s just been non-stop.

“The whole square is up in arms about it.

“The amount of abuse that’s been thrown about has been disgusting.

“I’m exhausted, but there is one positive in that the whole community has come together in this square from rich people to middle class and everyone else.”

The flat’s popularity for party goers surged after people shared its location on Facebook, and despite the landlord changing the locks on Tuesday night, revellers came back and kicked the locks open in an attempt to gain entry again.

The resident said: “They smashed the door in last night, so when we finally thought it was all going away, it was back again.

“It’s just been frightening and horrendous.

“It was like a horror movie.

“And just when I thought I could relax, it’s not ended.”

Ann Smith, who lives in the square, believes the blame lies with the party-goers and not the occupant of the flat.

She first noticed a problem on August 2.

She said: “For us, we’ve been hearing noise when the older ladies in the square have been going to bed in the evening and then they get woken up about 1am or 2am.

“And then we get disturbed again at about 5.30am to 6am when they’re all going away.

Mrs Smith wants landlords to ensure problems like these do not arise.

“There are 110 properties in this square in just 24 buildings,” she added.

Another neighbour, who did not wish to be named, said: “It’s been really tough for us.

He added: “It’s been going on for months and it’s been constant.

“We’ve had partying, violence – the lot – and there have been a number of meetings to try and resolve it.”

Another neighbour added: “It’s a lovely place and a quiet place to live, so it has been a very unusual occurrence.”
