Ghaziabad, June 23 (ANI): The Central Bureau of Investigation (CBI) has been given additional four days custody of Krishna in the Aarushi-Hemraj murder case here today.

Krishna, worked as a compounder in 14-year old Aarushi’s dentist father Rajesh Talwars clinic.

The agency arrested Krishna on June 13, while stating he had confessed to his involvement in the murder of Aarushi and the Talwar family’s domestic help Hemraj.

Dr. Talwar, has already been under arrest since May 23 after Noida police claimed that he had murdered Aarushi and Hemraj on the intervening night of May 15-16.

Aarushi, was found murdered in her sector-25 Jal Vayu Vihar apartment in Noida on May 16.

Before the CBI took over the case, the Noida police initially named her family’s domestic help Hemraj as the prime accused but backtracked when his body was found on the roof of the building the next day.

The CBI has questioned a number of people but is nowhere near zeroing in the motive for the crime.

CBI has also interrogated Talwars family friends Durranis` domestic help Rajkumar and Talwars other domestic help Bharti. (ANI)
