More than 200 Muslim inmates at the jail are believed to have been offered the meat which is strictly forbidden by Islam.
The sandwich was one of three options on the menu card which was created to cover the religious festival during which Muslims are required to fast during daylight.
They later complained to prison officers on duty but say they were told that the menus had been printed in error. Yet when they opened the sandwiches, having ordered cheese, some claim they were still filled with boiled ham.
The Muslim prisoners are now launching legal action, insisting that their human rights were breached and could each be entitled to up to £10,000 in compensation if they win their case at court. Link
