The CBI has asked the UP Police to provide pieces of crucial evidence relating to the murder of teenaged girl Aarushi Talwar - the bedsheet on which she was found dead and her room's doormat - as it continues the probe into the nearly two-year old case.
Citing the importance of the bedsheet and the doormat, a senior forensic official said the bedsheet might have some seminal stain or blood stain or any other forensic evidence and, if investigated, they might give a clue of the murderer.
Earlier, the CBI had asked for the same from the parents of Aarushi after they had undergone narco test at Gandhinagar Forensic labrotary recently, they said.
Aarushi Talwar was found dead with her throat slit on May 15, 2008, at her home at Jalvayu Vihar in Noida. Their domestic help Hemraj, initially suspected of the crime, was found dead on the roof-top.
The CBI team investigating the case had charged the UP police, who had first probede the case, with having destroyed 90 per cent of the evidence at the crime scene.
The forensic scientist said the UP police did not cordon off the crime scene and "as such when we went to capture the finger prints, we found many people as the media and other people were walking up and down all over them."
Sources in the UP police claimed all the evidence collected during the probe was handed over to CBI and there was nothing more to be shared with the agency.
