The police also seized a charger and a notebook during the inspection, raising questions about security and the use of prohibited electronic devices inside the prison.
The raid, carried out by around 100 Central Crime Branch personnel with Chief Minister D K Shivakumar’s approval, uncovered several violations, according to Kharge.
The phone was seized during a five-hour raid conducted by the Central Crime Branch (CCB) on Tuesday at the High Security Parappana Agrahara Central Prison.
