High court enforcement officers armed with sledgehammers and battering rams battled to evict more than 100 people from the Sweets Way housing estate in north London so that a developer controlled by the private equity baron Guy Hands can redevelop the site.

There were violent clashes between court officers, police and protesters as a judge ordered the repossession of the home of the last tenant living on the former Ministry of Defence housing site in Whetstone. The action left a disabled father of four, Mostafa Aliverdipour, facing eviction. Late on Wednesday, protesters erected barricades around his house.

Hossein Aliverdipour, 21, Mostafa’s son, said the Barnet council’s housing arm would not offer a replacement home suitable for his father’s disability. “He is a full-time wheelchair user and the doors aren’t wide enough for it. It is a three-storey house and there is no downstairs bathroom for him,” he said. “If they can do this to a disabled man, imagine what they can do to a normal family.” Mostafa Aliverdipour’s case is expected to be heard in court on Wednesday afternoon.

The confrontations came six months after the estate was occupied by housing activists protesting against the eviction of several families, many of whom had been homeless. Annington Homes plans to build 282 properties on the site, 80% of which will be for private sale. The dispute over the future of the properties came to national attention when Russell Brand joined a protest sleepover at the occupied homes. Sweets Way has since become a focus for national campaigners concerned over the lack of affordable housing.

Earlier in the day, police dog teams, ambulances and fire engines were placed on standby as dozens of squatters who have been occupying the homes since March took to the roofs of the houses and refused to come down. Officers played cat-and-mouse with the squatters, trying to intercept the bags of food and drink being thrown up to them on the roof.

Those evicted described how eviction officers smashed down their doors without warning and gave them 10 minutes to leave. They said there had been several violent confrontations, with some people being carried out, including one man in his 70s. “We were scared,” said Carolina, 33, who is six months pregnant and said she now had nowhere to sleep. “They pushed in the doors and about eight of the officers came into each house. It is just unfair. Winter is coming and the number of homeless is growing.”

One couple, Jay and Bibi, who are in their early 20s and had squatted in the properties for a couple of months, told the Guardian they were homeless again as they left the estate with a duvet and a few bags of belongings. “We are going to get a train into central London and try and sleep under a building,” Jay said. “Some people have places to stay, but we are homeless. We are going to sleep rough. It is just part of this corrupt system. When I was working, if I had been paid double, worked twice as many hours and saved everything, I would only have been able to afford a £100,000 house, and what can you buy for that?”

A spokesman for Annington Homes, the property company controlled by Guy Hands’ Terra Firma investment operation, said it “very much supports the argument for more homes, both in London and elsewhere, although there is a need for development to achieve this”. He added: “It is regrettable when homes need to be demolished, but Annington’s decision to develop will see an increase in the number of homes by 100%.”

A statement from Annington Property Limited said that Barnet Homes had offered Aliverdipour a refurbished house that “fully meets his, and his household’s needs”.
