A special CBI court trying Aarushi murder case on Wednesday extended validity of non-bailable arrest warrant against accused Nupur Talwar till April 30 as requested by the top investigating authorities.

Nupur Talwar skipped the court hearing recently while her husband Rajesh Talwar was present. Nupur and Rajesh, parents of murdered Aarushi, are the prime suspects in the case.

The CBI made a flip-flop on its statement over accused Nupur's alleged absconding following warrant against her.

The CBI officials informed the Supreme Court bench on Friday that the authorities had intelligence about Nupur's hide-out but didn't arrest her as the plea challenging the warrant was still pending in the apex court.

However, the probing agency said in a Ghaziabad court on Wednesday that Mrs Talwar was not arrested as her whereabouts were unknown by the officials, when they conducted raids at her residence.

Noting the SC direction to the CBI, the authorities sought for the extension of validity of a non-bailable warrant against one of the accused. The apex court on Friday instructed the CBI to refrain from arresting Nupur until a SC bench hear the plea by Nupur seeking for an anticipatory bail and stay on non-bailable warrant.

Chief Justice of India Mr S.H. Kapadia will hear the plea of Nupur by this week.

Early last week, a Ghaziabad court issued a non-bailable warrant against Nupur after she violated the deadline to produce herself before the court of law. Despite her lawyer's request to exempt her from appearing as the plea against the apex court's order to face trial awaits hearing, the court issued a non-bailable warrant against her.

The CBI officials, who are probing into the four-year-old double murder case, reached Nupur Talwar's residence last week order to take her into the custody after getting warrant. However, probing agency did not find her at her residences in Delhi and Noida.

In 2008, Aarushi, a 14-year-old girl was found dead in her bedroom at her residence in Noida, Uttar Pradesh, with her throat slit. Hours later, another dead body was found on the terrace, which was identified as Hemraj, a house maid.

The double murder case was handed over to the CBI that indicted the parents' hand.
