The protest follows a similar protest being staged by female inmates last week.
Several female inmates at the Welikada prison staged a protest on the roof last week but suspended the protest a day later.
The inmates had demanded that their concerns be looked into, including delays to hear their cases.
The protest last week was suspended following discussions held between the female inmates and the authorities.
An official was appointed last week to look into the issues faced by female inmates of the Welikada prison. (Colombo Gazette)
