The Delhi police on Friday filed a charge sheet in a trial court against the Ansal brothers in the Uphaar movie hall fire case, saying there is evidence to prove the brothers tampered with judicial records.

The issue also came up before the Delhi high court with the police claiming to have got hold of substantial evidence against Sushil and Gopal Ansal and four others for tampering with the records of the fire that claimed 59 lives in the posh south Delhi cinema hall in 1997.

The Ansals had appealed in the high court against their two-year jail term.

The documents said to have been tampered with include a police memo giving details of recoveries immediately after the incident, Delhi Fire Service records pertaining to repair of transformer installed inside Uphaar, minutes of the managing director's meetings and four cheques, the charge sheet said.

Out of the six sets of documents, a cheque of Rs 50 lakh, issued by Sushil Ansal to self, and minutes of the MD's meetings prove beyond doubt that the two brothers were handling the day-to-day affairs of the theatre at the time of the fire, it said.

The Ansal brothers had argued they were not handling the affairs of the theatre as they had already resigned from the board of directors of M/s Ansal Theatres and Clubotels Pvt Limited, which then owned the cinema hall.
