Patna: A Central Bureau of Investigation team on Monday visited the Muzaffarpur Bal Grih where at least 34 minor girls where raped, and the Khudiram Bose Central Jail hospital where Brajesh Kumar Thakur, the prime accused in the case, is lodged.

Brajesh, proprietor of the Seva Sankalp and Vikas Samiti that ran the Balika Grih since November 1, 2013, was arrested on June 2 but spent just a few days in a prison cell.

He complained of chest pain and was shifted to Sri Krishna Medical College and Hospital (SKMCH) on June 9 and was shifted back to the jail on June 27.

Since then, barring for a few days, he has been lodged in the jail hospital over complaints of diabetes, hypertension and back pain.

Brajesh's hospital stay, coupled with photographs showing him grinning from ear to ear in custody, raked-up allegations that he has been able to game the prison system.

Reporters on Monday asked chief minister Nitish Kumar about it.

He directed the question towards director-general of police (DGP) K.S. Dwivedi, who was also asked about why the police failed to take Brajesh on remand.

"Prisoners are sent to hospital by court on the report of doctor," the DGP said.

"Brajesh was sent to hospital on the basis of his illness. We had requested the court to take him on police remand, but the court did not allow this as he was already in judicial custody. However, the court allowed us to interrogate him inside the jail, which we did."

Muzaffarpur civil surgeon Shivchandra Bhagat also sent a two-doctor team to the jail hospital.

"We sent two physicians on the request of jail's medical officer to evaluate the medical condition of Brajesh and give advice. He is suffering from diabetes and high blood pressure. Our doctors recommended use of insulin and suggested that some orthopaedic should see him for back pain," Shivchandra said.

The CBI officials also started going through the call detail records of three mobile numbers used by Brajesh, sources said.

The agency, a highly placed source said, is "likely to interrogate Brajesh soon".

Muzaffarpur senior superintendent of police (SSP) Harpreet Kaur said all documents pertaining to the Balika Grih case have been given to the CBI.

"We had taken out call details of Brajesh's mobile numbers too and were investigating it from various angles. We were also in the midst of probing his financial transactions. However, we had to stop it after the CBI took over the case," the SSP The Telegraph on Monday.

The police are still investigating the case that was registered against another shelter home (for women, as opposed to minor girls of the Balika Grih) in Muzaffarpur in the last week of July and is trying to find the its boarders.

Another team, comprising three officials of the Press Information Bureau (PIB), also arrived in Muzaffarpur on Monday to investigate the three newspapers Brajesh and his family members publish. The PIB team is led by its Patna director Dinesh Kumar.

"Our officials will scour everything related to these newspapers, including their printing, distribution, circulation, and staff," a PIB source said.

Sources said that the newspapers fraudulently showed circulation as high as 62,000 to get advertisements from the state and central governments.

"We stopped giving advertisements to from June when the Muzaffarpur case came to light," said information and public relations department secretary Atish Chandra.
