Dr. Rajesh Talwar, prime accused of Noida double murder case was produced in Gaziabad Special CBI Court and his judicial custody is extended by 14 days. CBI told the court that it wanted to conduct a polygraph test of Dr Talwar on June 20.

The judicial custody of Rajesh Talwar who was arrested on May 23 by Noida police for allegedly murdering his teenage daughter Aarushi and domestic help Hemraj on the intervening night on May 15-16, was ended on Thursday.

CBI suspects that Krishna, the compounder of Rajesh Talwar, has killed both the victims, Aarushi and Hemraj but CBI told the court that Dr Talwar’s involvement in the murder of Aarushi and Hemraj was not ruled out.

Krishna was arrested by the CBI on June 13 after reports of various scientific tests were received by the CBI.

Forensic experts also believe that it is a case of lust killing only. Attacks on Aarushi’s face and slitting of her throat after she was killed shows that the murderer had a keen desire to kill her.

Krishna has not accepted the murder yet but he said that Hemraj asked for his Khukri (sharp Knife) on May 14 and he gave the same to him on May 15. He was also helping the investigating agency in exploring the murder weapon, which was still not found.

Court on Tuesday remanded dentist Rajesh Talwar’s compounder Krishna in six days of CBI custody as the agency claimed he was required for recovery of weapon used in murders.

Dr Anita Durrani and Dr Praful Durrani who are family friends and professional associates of the Talwar couple are also interrogated in the case. On Thursday, CBI sleuths detained the domestic help of the Durranis, Rajkumar, for questioning.

Rajkumar, who was earlier released by the agency on Wednesday night, was subjected to a lie detector test.

CBI has also sought bank account details of Rajesh Talwar on Wednesday.
