Some 18 female guards at one single jail were fired for having affairs with inmates.
The sexual relationships took place at HMP Berwyn, in Wrexham, Wales, over the last six years.
Three of the women ended up in court and were jailed, and the rest were revealed through Freedom of Information requests from The Mirror
Jennifer Gavan, 27, was jailed for eight months in December after smuggling a mobile phone for her lover Alex Coxon, 25, so she could send photos of herself to him via Snapchat.
She was also caught kissing him during the relationship that went on from April to July 2020.
The officer pleaded guilty to misconduct in public office after she accepted £150 to bring in the phone.
In 2019, Gunn was jailed for one year after having a fling with ‘dangerous’ inmate Khuram Razaq, 29.

The criminology and psychology graduate made numerous sexual phone calls to him while he was serving a 12-year sentence for conspiracy to rob, and smuggled in a pair of her knickers for the prisoner.
A search of her bedroom revealed snaps of the pair kissing and hugging while in his cell.
That same year, Emily Watson was jailed for one year for performing a sex act on prisoner John McGee.

They had been alone together in his cell on three occasions, when she performed a sex act on him twice and had intercourse once.
Staff have since been given corruption prevention training and the prison’s security has been enhanced.
A Prison Service spokesman said: ‘The overwhelming majority of Prison Service staff are hardworking and dedicated and we will not hesitate to punish those who break the rules.
‘Over 500 members of staff at HMP Berwyn have undertaken corruption prevention training in the last 18 months and our enhanced security is protecting the prison against attempts to smuggle illicit items inside.’
