A woman has been charged with misconduct over a video showing a female prison officer having sex with an inmate in a Wandsworth jail cell.
Linda De Sousa Abreu, who was revealed to be the woman in the video by MailOnline on Friday, will appear in custody at Uxbridge Magistrates' Court on Monday, the Met Police said.
The force launched an investigation after it was made aware of the footage on Friday before arresting a woman and taking her into police custody on the same day.
The shocking clip sees the 30-year-old wearing uniform and 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 friend who is smoking while recording says: 'Guys we've made history, this is what I'm telling you.'

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!'
