Ghaziabad, June 16 : Indian police will have to learn the art of crime scene management, said Central Bureau of Investigation Special Director M L Sharma while inaugurating a course on Evidence Recovery, Preservation and Exploitation jointly conducted by the CBI and the America's Federal Bureau of Investigation (FBI) today in New Delhi.

Sharma said, "In the Aarushi murder case, every time the CBI team visited the crime scene, some new evidences were coming up. Some time it is liquor bottle, some time a blood soaked pillow and some time other evidence. The fact is that the crime scene was not inspected properly."

He said the CBI probe into the Aarushi murder case was proceeding in the right direction, but refused to give the deadline to crack the case.

According to latest reports, the CBI has also questioned Raj Kumar, the domestic help of Anita Durrani, a friend of the Talwars and seized his mobile phone. His mobiles were sent for forensic examination.

Detained Talwar's compounder Krishna was taken to Noida and searches were again conducted to trace the mobile phone of the two victims. A servant of Talwars' neighbour was also questioned.

The CBI had arrested Krishna on the basis of reports of polygraph test and narco-analysis test conducted on him at the Forensic Sciences Laboratory in Bangalore on June 12.

The police arrested Rajesh Talwar on May 23, and suspected that he was responsible for the murder. The police alleged that Talwar first killed Hemraj and then Aarushi. (ANI)
