A woman is to appear in court after a video was shared on social media allegedly showing a prison officer having sex with an inmate in a cell.
Linda De Sousa Abreu, 30, of Fulham, south-west London, has been charged with misconduct in public office, the Metropolitan Police said.
She is in custody and will appear at Uxbridge Magistrates’ Court on Monday.
A police investigation was launched on Friday after officers were made aware of a video said to have been filmed inside HMP Wandsworth.
An arrest was made later that day and De Sousa Abreu was charged on Saturday, police added.
