On Wednesday, the family members of the deceased filed a petition in the single bench of Justice Amrita Sinha demanding a detailed and independent investigation into the case.

As the case came up for hearing on Thursday, the state government's counsel rejected claims of custodial torture and said Haldar died due to increased levels of urea and creatinine in his body.

When Justice Sinha asked for the CCTV footage of the Dholarhat police station, where the alleged custodial torture took place, the state government counsel pointed out that the cameras were not working for a long time.

After this, Justice Sinha ordered to preserve the video recording of the post-mortem of the victim's body.

The matter will be heard again on Friday.

Halder died on July 8, just four days after he was released on bail by a district court in South 24 Parganas district on July 4.

On Thursday, the victim's family members informed the court that they had to pay a bribe of Rs 1.75 lakh to the police to ensure his bail.

The victim was arrested by the police on June 30 on charges of jewelery theft. Family members alleged that he was beaten in custody, which was evident from the injuries visible when he was produced in the district court on July 4.

He was granted bail that day and sent to a local hospital, where he was released after first aid.

The victim's mother Taslima Bibi claimed that when he returned home his condition started deteriorating, following which he was shifted to a hospital in Kolkata.

He was later admitted to a private nursing home for further treatment. However, he died late on Monday night.
