The Central Bureau of Investigation has formed a three-member core team to re-investigate the Noida double murder case after the agency drew flak for failing to file a chargesheet within the stipulated 90 days leading to release of three accused.

Coverage: Aarushi murder case

Sources in the investigating agency said the three member team would carry out re-investigation from the beginning and has been mandated to question people accused in the murder of Aarushi and her domestic help Hemraj and verify all evidence.

The agency, which took over the probe on May 31 this year into the mysterious double murder, has been maintaining investigations were not complete despite its former Director Vijay Shanker claiming that the agency had nearly cracked the case.

Following the murder of 14-year-old Aarushi Talwar and her domestic help Hemraj on the intervening night of May 15 and 16, Aarushi's father Rajesh Talwar was arrested by Noida Police on May 23.

However, after the case was taken over by the CBI, the agency gave a clean chit to him on July 11. The sources said the three-member team would piece all the evidences together and ascertain whether some gaps were left earlier while probing the blind murder case.

The failure of the CBI to file the chargesheet led to the release of Raj Kumar, domestic help of a Talwar family friend, Krishna, compounder of Talwar and domestic help his neighbour Vijay Mandal.
