In a major setback to Nupur Talwar, a special CBI court in Ghaziabad today issued a non-bailable warrant (NBW) against her, for failing to make an appearance in the court during the hearing of her daughter Arushi Talwar's murder case. However, Aarushi's father Rajesh Talwar was present in the court. The special judge has fixed April 18th as the next date for hearing.
