The Central Bureau of Investigation on Wednesday questioned the Durranis, friend of the Noida dentist couple Rajesh and Nupur Talwar, whose teenaged aughter Aarushi was murdered allegedly by her father, and sought bank account details of Rajesh Talwar.

The Durranis -- Praful and Anita -- were called to the CBI headquarters on Wednesday evening and examined by psycoanalysts from Forensic Sciences Laboratory and All India Institute of Medical Sciences.

The agency, which has been struggling hard to find the motive behind the murder, meanwhile, continued questioning the Rajesh Talwar's compounder Krishna.

The discrepancies in Krishna's his statements to the CBI is giving rise to the suspicion that either Krishna was the person who allegedly carried out the gruesome murders or was actively part of the criminal conspiracy hatched to carry out the killing.

The CBI has also sought details of bank account of Rajesh Talwar of the last one year.

Talwar will be produced before a Ghaziabad court on Thursday when his 14-day judicial custody ends.

"We will press for his bail as the CBI has not found anything against him," Talwar's lawyer Praveen Kumar Rai said.

The counsel is planning to take the CBI to the designated court in which the agency has claimed that Krishna was involved in the killings and that it was looking for two to three accomplices.

This means that the CBI has nothing against Talwar, the counsel said.
