Punjabi singer-actor Diljit Dosanjh has reportedly received a threat from Khalistani outfit Sikhs for Justice (SFJ) after he touched Amitabh Bachchan’s feet on ‘Kaun Banega Crorepati’. SFJ chief Gurpatwant Singh Pannun accused Diljit of 'insulting victims' of the 1984 riots and warned to shut down his upcoming Australia concert.
