The notorious Strangeways prison is currently under lockdown amid claims that inmates have not been allowed to shower or exercise for a number of days.
It is understood that prisoners have been confined to their cells since June 6, with families also prohibited from visiting their loved ones until June 10.
Relatives state that they have been informed by family members inside the Manchester prison that they have not been allowed out of their cells for any reason and are having food brought to their door, Manchester Evening News reports.
