A 45-year-old man has been shot dead in Madhya Pradesh's Gwalior district by two aides of Canada-based gangster Arshdeep Singh Dalla. The two accused, who were also involved in the murder case of a Sikh activist, Gurpreet Singh Hari Nau, in Punjab's Faridkot last month, have been arrested. The victim in the Gwalior shooting, identified as Jaswant Singh Gill, was undergoing life imprisonment in a 2016 murder case and was killed on Thursday. The murder was caught on CCTV.
