Trudeau said last week Canada was pursuing "credible allegations" that Indian government agents may have been involved in Nijjar's murder. The Indian High Commissioner to Canada, Sanjay Kumar Verma, said concerned authorities have been informed of the protests. Nijjar, who worked as a plumber, left the north Indian state of Punjab a quarter-century ago and became a Canadian citizen. He has supported the formation of an independent Sikh homeland, called Khalistantan, to be created out of Punjab. The Canadian government has amassed both human and signals intelligence in a months-long investigation into the Sikh separatist leader, CBC News reported last week, citing unidentified sources.
