Dentist Nupur Talwar, who is a key accused in the Aarushi-Hemraj double murder case, will be released from Ghaziabad's Dasna jail on Tuesday.
The Supreme Court on Sept 17 granted her bail in connection with the case.
Nupur is a key accused in the case along with her husband dentist Rajesh Talwar in the murder of their daughter Aarush and domestic help Hemraj.
The Supreme Court on Aug 13 had rejected the bail plea of Nupur Talwar. The CBI had opposed Nupur´s bail. But later she was granted bail.
Aarushi´s mother Nupur surrendered before the Ghaziabad court on Apr 30. She has been in jail since then.
Teenager Aarushi Talwar was found dead, with her throat slit, at the Talwar residence in Noida in the morning of May 16, 2008. The body of Hemraj, Talwars´ domestic help, was found on the terrace the next day.
The case has since spiralled into one of the country´s biggest unsolved cases, with a prolonged investigation marked by admissions of lack of evidence and dramatic twists.
Nupur and Rajesh Talwar maintained that they are innocent, and are being framed by the CBI since the agency has not been able to track down the real killers.
