 On 4 August 1992, Indian police claimed to have killed Khalistan Liberation Force's new chief Navroop Singh Dhotian and four other Sikhs in a 20-hour gun battle but later on 29 August 1992 declared that Mr Navrup Singh Dhotian is still alive.As per Indian Government's request, Daya Singh Lahoria of the Khalistan Liberation Front was extradited from the U.S to India to face court cases.Lahoria's trial took approximately five years but at the end he was acquitted of the charges because his complicity could not be proved.
