Police on Thursday said actor Sheezan Khan was being questioned to ascertain what exactly happened on the set of a television show in Maharashtra’s Palghar district where his co-star Tunisha Sharma allegedly committed suicide last week. Though Khan had ended his relationship with Sharma, they were on good terms with each other and used to speak regularly, an official from Valiv police station in Palghar said. Sharma, 21, who acted in the show ‘Ali Baba: Dastaan-E-Kabul’, was found hanging in the washroom on the set of the serial on Saturday near Vasai in Palghar.
