Ghaziabad, Sep 26 (IANS): Dentist Nupur Talwar, mother of slain teenager Aarushi, walked out of prison on bail following an order issued by a special court here Tuesday. She was arrested April 30.

She stepped out of the Dasna jail around 7 p.m. after a Central Bureau of Investigation (CBI) special court issued orders to release her on furnishing a bail bond of Rs.200,000, in addition to two surety bonds of Rs.200,000 each.

The local court issued the release order after the Supreme Court Sep 17 granted her bail and asked the trial judge to release her Sep 25.

Sporting an orange suit, Nupur Talwar looked calm as she came out of the jail. She was received by her dentist husband Rajesh Talwar, who himself is out on bail.

Nupur Talwar's brother-in-law Dinesh Talwar, along with other family members and relatives were also present.

Police escorted her to a car waiting outside the jail. As her car moved towards National Highway-24, a police vehicle followed it.

Nupur Talwar and her husband are accused in the murder of their daughter and destroying evidence.

Aarushi, 14, was found murdered at her parents' Noida residence May 16, 2008. The body of her domestic help Hemraj was found the next day on the terrace of the house.

During the hearing before CBI Special Judge S. Lal, the CBI submitted an application before the judge submitting that they wanted to give some fresh documents as evidence.

Defence lawyers opposed the CBI submission and requested the court to grant them time to oppose it. The court would next hear the case Sep 27.

In a related development, police Tuesday said the former investigation officer and one of the prime witnesses in the Aarushi-Hemraj double murder was killed by a speeding truck Sep 20.

Sub-inspector Jagvir Singh Malik was among eight policemen who were killed after being hit by the truck around 11 p.m. on National Highway-24 near a picket where they were posted.

Malik was appointed the investigation officer after Data Ram Nanoria and held the responsibility for three days.
