Punjab Congress president Amarinder Singh Raja Warring has reportedly received a death threat from Pakistan-based Babbar Khalsa International (BKI) terrorist Harwinder Singh Sandhu alias Rinda. According to police officials, the message warned Warring to refrain from political campaigning until November 11, the polling date for the Tarn Taran Assembly by-election. Congress leader Rajvir Singh Bhullar also received a similar threat. Sources said the warnings surfaced after Warring’s remarks about former Union Home Minister Buta Singh.
