Chief Metropolitan Magistrate Satish Kumar Arora sent the accused to CBI custody till December 2 after the probe agency claimed that he was required for further interrogation with regard to a forensic report released in the matter.
The court, however, turned down CBI's plea seeking seven days custody of Aman, who was produced before the magistrate on expiry of the previous custody, and allowed it for three days instead.
A magisterial court had on November 26 granted CBI the custody of Aman for three days after the agency claimed that he was required for custodial interrogation to unearth the entire conspiracy behind the crime.
Aman was arrested on November 25 for the alleged murder of his 27-year-old wife Sara, who had reportedly died in a car accident in Firozabad on National Highway 2 in July last year. However, he had escaped unhurt.
