Officers from the Prison Corruption Unit at the North West Regional Organised Crime Unit (NWROCU) have arrested two women aged 29 and 32, who are employed to work at HMP Berwyn, Wrexham on suspicion of misconduct in a public office and possession with intent to supply drugs.
The 29 year old was also arrested on suspicion of money laundering.
Officers investigating the incident executed warrants at properties in Flint and recovered Class B drugs and designer jewellery and clothing.
A coordinated search was also conducted in the prison, during which Class A drugs were recovered.
Detective Inspector Dawn Hampson from NWROCU said: “These arrests are another great example of the ongoing work between the North West ROCU and HMPPS to tackle the problem of corruption within prisons. The vast majority of people who work in prisons are upstanding, honest individuals, so it’s important we continue to take action against the small minority who are involved in corrupt activity.”
