Mr Pancholi, 21, who dated the actress for an year, was arrested on June 11, 2013. His family and lawyers say there is no evidence that links him to Ms Khan's hanging at her home on June 3, 2013.
Six days later, her family supplied a letter to the police in which the troubled actress appeared to be venting about a romantic relationship.
The letter does not name Mr Pancholi or anyone else.
Mr Pancholi is the son of Bollywood stars Aditya Pancholi and Zarina Wahab.
