With Khalistani sympathizer Amritpal on the run since March 11 and Punjab police launching a crackdown against his "Waris Punjab De", Kishtwar police on Thursday said they have cancelled the licence of the gunman of the fugitive leader after it was renewed by allegedly using fake documents. "A gun license was issued in the name of Virendra Singh in 2014. His license was cancelled after Punjab police wrote to Kishtwar DC. He had used fake documents to renew the license. It was found that a gun license was misused," SSP Kishtwar Khalil Poswal said.
