Hoshiarpur, July 6 -- The Punjab Police special investigation team (SIT) probing the 2015 Behbal Kalan firing case on Sunday once again issued summons to senior BJP leader and former Union minister Vijay Sampla to appear on July 6. Sampla was previously summoned on June 28, but failed to turn up. Before this, he had appeared before investigators in Jalandhar on June 23. Responding to SIT's fresh summons, Sampla questioned why he was being singled out, especially since the police had failed to provide copies of the documents based on which he was being asked to appear repeatedly. Reiterating his willingness to cooperate, Sampla said he had already informed the SIT in writing that owing to prior unavoidable commitments, he would be unable to appear on July 6, but would make himself available on July 7. The SIT summons come amid fresh momentum in the investigation. On June 11, the SIT recorded a statement from former Akal Takht jathedar Giani Raghbir Singh, who claimed SAD chief Sukhbir Singh Badal had previously admitted to wrongdoings before the temporal seat. The probe traces back to October 14, 2015, when police opened fire on unarmed protesters demonstrating against the desecration of the Guru Granth Sahib at Bargari, killing two people. On July 3, the SIT visited Bargari and Behbal Kalan villages to recreate the crime scene.HTC...
