Linda De Sousa Abreu Wandsworth Prison Officer Recorded Kissing Inmate

Police have arrested a woman after a female prison officer was filmed having sex with an inmate in an HMP Wandsworth jail cell.

The suspect is being held on suspicion of misconduct on public office after police arrested her yesterday.

It comes after footage emerged of a prison officer having sex with an inmate in his prison cell.

The woman in the video, who MailOnline revealed was a swinger named Linda De Sousa Abreu, is seen wearing uniform during the explicit clip, which begins with her performing a sex act on an unidentified prisoner at the Category A jail in south-west London.

The footage, which MailOnline understands to be recent, then shows her having sex with the prisoner while his cellmate films on a mobile phone. Footage of the cell shows a TV and piles of clothes heaped over a bunk bed.

The prison officer's radio, left on a side table, crackles constantly with her colleagues heard on the other channels above the din of the other prisoners on the landing unaware of what is going on in the cell.

At one point, someone appears to try to come into the cell, at which the man filming, can be heard saying to the person on the other side of the door 'give me a minute, one second.'

The prisoner filming tells his friend to carry on and then pans the camera round momentarily and, grinning, says: 'This is how we roll in Wandsworth.'

He then tells his friend having sex: 'You know you're gangster innit!'

MailOnline revealed on Friday that the woman in the video was De Sousa Abreu who is understood to have recently quit her job as a prison officer in the South London jail following the scandal.

Her sister, Andreina, told last night how she warned her not to mix her lifestyle with her work and said she was now 'suffering the consequences'.

She said Linda and her husband Nathan Richardson, now 29, were stars of Channel 4's Open House: The Great Sex Experiment in which couples pushed the boundaries of the relationships at a luxury country escape.

And the Brazilian-born model did not hold back during the show even getting involved in a 15-person orgy with the fellow contestants.

The couple also boast an OnlyFans account, under the alias Linda La Madre which charges $10 a month for racy content of her and her husband.

The then personal trainer from Fulham explained during the Channel 4 documentary: 'Monogamy is a social construct that I think needs to be dismantled.

'Opening up our relationship has allowed us to form a deeper connection with each other.'

One of her co-stars Shanice, who was exploring the idea of having a foursome with pair on the show said: 'Linda is fire...crazy sex appeal'.

At the time of filming the couple had been together for nine years and in an open relationship for three of those.

And her sibling, who is a personal trainer from London, told MailOnline tonight how she had to block fans of her sister from her own social media after the racy show. Linda is also believed to have an explicit OnlyFans account too.

Andreina said: 'She's a swinger. She was on a Channel four programme called Open House. I never saw it. It's not the sort of thing I'd watch with my little sister in.

'I have built up a big community on my own social media – I preach fitness and God – but when her fans found her, they found me and they were sending me messages and I was blocking everyone because it's not something I wanted to be associated with.'

Linda's OnlyFans reads: 'I am a happily married sexy latina who wants to share hot content with you. Experience my real life, real love, real sex and real orgasms!

'We believe in authenticity, all our content will be genuine and we'll never fake it because we want you to enjoy watching it as much as we'll enjoy making it!'

Her sister said she only found out Linda worked for the prison service at the start of the year and said the pair had a heart to heart.

She explained: 'I've had my say with her, I was very brutally honest with her about her behaviours.
