The Delhi High Court had ordered the police to register a case in this regard on May 5, 2006, and ordered it to complete the investigations within three months.

'There appear to be several circumstances relied upon by the prosecution to prove the conspiracy involving the accused. These include the call data conversations between Dinesh Chand Sharma (court staffer who was dismissed for tampering with evidence) and Prem Prakash Batra, providing employment to Dinesh Chand Sharma after his dismissal from A-Plus Security and Training Institute, applying fluid over his name in the attendance register, giving him double salary by paying cash and so on,' the judge said in his judgement.

The police lodged an FIR May 17, 2006, and arrested Dinesh Chand Sharma.

The police later filed a chargesheet in the court naming the Ansal brothers and two others as accused. Additional Chief Metropolitan Magistrate had issued summons to all the accused on Feb 15, 2008, after which the Ansal brothers approached the Delhi High Court, which stayed the trial court proceedings on April 30, 2008.

At least 59 people died of asphyxia following a fire in the basement of the Uphaar cinema hall on June 13, 1999. The Ansals are owners of the cinema hall.
