"Rajkumar's parents are in Nepal. Moreover, Krishna's family also hails from Nepal. So they have gone there," Rajkumar's lawyer Naresh Yadav said.

Krishna, compounder of Noida dentist Rajesh Talwar, is a prime accused in the murder of Aarushi and her domestic help Hemraj on the intervening night of May 15-16.

Rajkumar, domestic help of Talwar's family friends Durranis, is another accused in the case. Their departure for their home has raised questions whether they would be available for questioning should the need arise.

Yadav said both of them have left for Nepal about a week ago and their leaving India would not hamper any probe as they would always be available for investigation.

"The CBI has their addresses in Nepal. It is a big agency and whenever they need them, CBI can contact both. In case they are not able to, they can ask me and I will bring them here," he said.

The double murder caught the attention of the nation following the arrest of Aarushi's father Rajesh Talwar by police for the crime. However, he was later released as the CBI has not found any evidence against him.

The CBI arrested Rajkumar and Krishna terming them as prime accused. But it could not file chargesheet within the stipulated time due to lack of evidence.

The delay in filing the chargesheet has enabled both the accused to get bail on September 12.

However, Krishna's lawyer Fateh Chand Sharma said he is very much in India and has not left the country.
