CBI said that when a dozen of golf clubs were seized from Talwars' residence on October 30, 2009, two golf clubs were found cleaner than others.

Agency's probe officer AGL Kaul had told the court that after killing Aarushi and Hemraj, golf club used in the crime was cleaned by Talwars.

CBI said that Nupur Talwar also cleaned Aarushi's private parts to hide “sexual relationship with Hemraj”.  

The agency said that statement of the then Noida SDM Sanjay Chauhan confirms that when he visited Talwars' residence morning after the murder, Aarushi's parents were looking nervous.
