Prison officers facing a £1,000 increase in their monthly rent claim they are now being threatened with eviction if they fail to sign a new contract.
The Wormwood Scrubs officers living in Bromyard Avenue and Alexander Close, Acton, have reportedly received new tenancy agreements which they must sign by the end of October or risk losing their homes.
This move comes just two weeks after the Gazette revealed the officers, who enjoy subsidised rent, are being forced to pay a price hike from to £150 to £1,150 after property developer Berkeley Homes bought the land.
Fears were raised by the Prison Officers' Association which believed this was a tactical move to drive people out in order to sell off the land for luxury redevelopment.
A friend of one officer - they are gagged by the Official Secrets Act - said: "They were sent out packs and told to accept the agreement and the rent and it was clearly communicated to them that if they don't sign by the end of October, they will lose their homes.
"There doesn't seem to be any progress and it's not right that they are being forced out in this way."
Brian Caton of the POA said they have written to the prison minister alerting them to the officers plight.
Mr Caton said: "There is no need to bully and threaten people; they should be looked after and not treated in such a bad way.
"These are public servants doing their job on behalf of society and it's wrong to over-burden them with further problems at home."
Angus Michie of Berkeley homes confirmed a number of prison officers have already signed the new tenancy agreements.
