The NIA will again question Punjab Police Superintendent of Police Salwinder Singh on Wednesday in connection with the Pathankot terror attack.
Singh will be questioned for the third consecutive day and is likely to be confronted with his cook Madan Gopal, who will be in Delhi on Wednesday.
Singh was questioned by the NIA for eight hours on Tuesday, during which contradictions were apparent in his statements to the investigators.
Meanwhile, the caretaker of a shrine in Punjab which an SP rank officer had claimed to have visited before being kidnapped by terrorists who attacked the Pathankot Air Force base hours later, was also summoned by the NIA on Tuesday.
