Because of the positive coronavirus cases among prisoners and staff groups, social visits have been stopped at the Salford prison.
A small number of prisoners and staff groups at the prison, a Category B prison in Agecroft, have positive coronavirus test results.
Matt Spencer, the prison warden, said: “Over recent weeks, efforts have been made at HMP Forest Bank to ease the lockdown measures put in place to defeat the coronavirus pandemic. However, we are now currently experiencing a small number of positive Covid-19 cases in both resident and staff groups at the prison and must take immediate and appropriate action to contain the local outbreak, as well as limit the risk of widespread infection.
“Following Public Health England (PHE) advice, a number of measures have been introduced to reduce movement across Forest Bank and to ensure the safety of all residents and staff. This includes suspending all social visits as of today (Wednesday, 14 October).
“This decision has been made reluctantly, knowing that it will impact the lives of many people; however, the prison remains a high-risk environment due to large groups of people living and working in close proximity to one another, so is necessary for a short period.
Forest Bank has capacity for 1,460 prisoners and is managed by Sodexo Prison Services.
