Inmates of the central prison in Parappana Agrahara here staged a protest inside the jail on Tuesday.
They are demanding parole facility, food from outside and allowing visitations from their family.
Several inmates refused to have breakfast, gathered at the ground and refused to take up work that they are assigned.
ADGP (Prisons) N S Megharikh and jail superintendent Somashekhar visited the prison and spoke to the agitating inmates.
After taking over, Megharikh imposed several restrictions following allegations of irregularities and favouritism to high-profile inmates.
