Uttar Pradesh Police started its probe on the premise that Hemraj had killed Aarushi and escaped from the crime scene.

After discovery of Hemraj's body on the terrace of Talwars' flat next day i.e. on May 16, 2008, under dramatic circumstances, the needle of suspicion came on Rajesh who was taken into custody by the UP Police.

The sensational allegations made by UP Police that killer was none other than father of the teenager who acted in rage after finding Aarushi and Hemraj in “objectionable but not compromising” position accentuated media attention.
