The Allahabad High Court on Wednesday deferred hearing on dentist Nupur Talwar’s bail plea in the Aarushi-Hemraj murder case till May 22.

The Central Bureau of Investigation (CBI) had filed an affidavit opposing Nupur’s bail plea, following which her counsel sought time to file a rejoinder.

The development comes on the fourth death anniversary of Nupur’s teenaged daughter Aarushi and domestic help Hemraj. Apparently killed on the intervening night of May 15 and 16, the teenaged girl was found butchered in her bedroom at Noida residence the following morning, while Hemraj’s body was recovered from the terrace of the building a day later.

After several twists and turns to one of the biggest murder mysteries, Aarushi’s dentist parents — Nupur and Rajesh Talwar — emerged as the prime suspects and they have been facing trial in a Ghaziabad court.

Apart from the Allahabad High Court, hearings related to the case are also scheduled on Wednesday, including one in the Supreme Court where the Talwars have filed a review petition as the couple hopes for not standing trial in the case. Another hearing was scheduled in a Ghaziabad sessions court where the Talwars face trial proceedings.

The CBI had on Tuesday handed over three probe-related CDs to Nupur’s lawyer after the Ghaziabad court’s order. The court was also likely to hear arguments on framing of charges, four years after the murders.

Nupur has currently been in judicial custody, lodged in Ghaziabad’s Dasna jail. Her husband has been out on bail.
