Showik, 24, was arrested by the Narcotics Control Bureau (NCB) in a drugs related case on September 4, as part of the investigations into the death of actor Sushant Singh Rajput almost six months ago.
The developments came around 110 days after Sushant Singh's death, coinciding with the AIIMS' report that has ruled out all speculation alleging the actor was murdered.
Terming as "absolute lie" that he had called her to his home in August 2013 and 'sexually harassed' her, Kashyap responded to police summons and recorded his statement with the investigating officer on October 1.
