Congress MP Jebi Mather also called for a thorough investigation into how the phone reached the barrack and whether political connections were involved.
โThis needs to be seriously looked into: how it happened. Maybe political connections were used,โ she told IANS.
Revanna is the grandson of former Prime Minister H.D. Deve Gowda, son of JD(S) MLA H.D. Revanna and nephew of Union Minister H.D. Kumaraswamy.
Phone found under bed
The Android phone was reportedly found hidden beneath Revannaโs bed in a barrack shared with another convict, Pratap Rai.
Parappana Agrahara police have registered an FIR and are investigating how the prohibited device entered the prison and who was using it. Rai has been named accused No. 1 and Revanna accused No. 2 in the case.
The wider raid reportedly resulted in the recovery of around 10 mobile phones, chargers and a pen drive from the barracks of high-profile prisoners, including actor Darshan and Pavithra Gowda.
The latest discovery comes just days after prison authorities conducted searches on 6 August, reportedly without finding a mobile phone in Revannaโs possession.
Investigators are now probing the source of the device and whether it was being used by Revanna or Rai. The episode has once again placed the spotlight on security inside Parappana Agrahara Central Prison and raised questions over how prohibited devices continue to find their way into the facility.
