Dainik Ganadoot Editor Sushil Choudhury (76), who allegedly masterminded the murder of three of its employees on May 19, could not be produced in court on Monday due to his alleged poor health.

Mr. Choudhury was admitted in the government G.B. Hospital after he complained of respiratory problem at Agartala central jail.

The Congress demanded a CBI probe into the murders. PCC president Sudip Roy Burman said the police had failed to make progress in the investigation.

“There is interference from certain quarters in the police enquiry. A few have been arrested but the police have failed to crack the mystery,” he said at a news conference. The party would stage protests across Tripura on Wednesday against ‘the reluctant approach of the CPI(M) government and the police in solving the case.’

This has been the first harsh reaction of the Congress though it had enforced a dawn-to-dusk strike in Agartala a day after the gruesome murders. The party is, however, silent on its legal wing members representing Mr. Choudhury when he was produced in court after his arrest on Saturday last.

Judicial Magistrate Shambhu Nath turned down both the remand and bail pleas after investigating officer Manas Paul failed to appear and submit the case diary. The court set Monday for considering the police remand of Mr. Choudhury on the merit of the case diary.

Mr. Choudhury fell ill in the jail on Monday morning. On the advice of doctors, the jail authorities took him to the hospital. Around noon, he was shifted to the ICU. Sources in the hospital said there was a move to refer him to a hospital outside the State as desired by his family members.

Additional Public Prosecutor Tapan Saha had said Mr. Choudhury needed to be thoroughly interrogated to clear at least eight issues that pointed the finger at him.
