Talwar was arrested on Friday after being questioned by the Noida police. He made many contradictory statements to police during his questioning. Dr Anita Durrani, who was working with Dr Talwar and is alleged to have had an affair with him, has also been detained. She has been named as an accomplice. Arushi's mother, Dr Nupur Talwar, has been arrested for abetment.
On May 21, Dr Rajeh Talwar had for the first time spoken to media saying, ''I have no information about the murder of Aarushi and am not involved in it in any way''. The police had maintained a stoic silence through out the case.
Aarushi, along with her servant Hemraj, was murdered on May 15. Even after four days of the gruesome murder of the 14-year-old girl, the Noida police had failed to break the case.
