The government has stepped in to bolster support inspectors found high levels of drugs and violence – including a high number of weapons and serious assaults compared to all other prisons.
“Dilapidated” conditions such as several broken windows and poor levels of cleanliness were also discovered along the rat infestation.
Inmates released early from their sentences in September to ease prison overcrowding described Strangeways, which was first built in the 1860s, as “disgusting” and rife with drugs and violence.
Some described rats “bigger than your hand” and easy access to drugs, with drones dropping contraband over the walls.
Lord Timpson recently visited the prison and met with the governor, and said staff were “working hard to reduce violence and improve conditions”.
“This action plan will ensure they have the support they need,” he said.
Under the prison’s measures, specialist staff will be appointed to better spot and support vulnerable prisoners at risk of self-harm.
Others will deliver new training to frontline officers to improve the management of violent offenders.
A new pest control strategy is being implemented and a team has been created to address urgent repairs.
The prison will also complete a review of the education it offers and redesign its curriculum.
