New Delhi, Aug 26 (ANI): The lawyer of actor, Sushant Singh Rajput's family, Vikas Singh said on August 26 that the actor was being drugged ‘without his knowledge’ is ‘ultimately what led to his death’.“When Sushant Singh Rajput's family got FIR registered, there was an impression that Sushant was being over-drugged on prescription drugs, that overdose too can disturb mental balance. But, now as disclosed by some reports that it was a banned drug. If it's a banned drug then it'll lead to abetment to suicide and murder. There'll be a Narcotics Control Bureau issue too. Scope of proceedings will widen substantially,” Vikas Singh said.
