Actor Rhea Chakraborty exploited boyfriend Sushant Singh Rajput financially, drugged his coffee to control his mind and discarded him like a "used tissue paper", the lawyer representing his father has alleged. "If Sushant was alive, they would not have had a problem if he spent Rs. 500 crore on her. But after his death the family realised that Rhea has just used Sushant - there was no love - used him like a tissue paper," lawyer Vikas Singh told NDTV.
