Additional Chief Judicial Magistrate of Barrackpore Mayukh Mukherjee rejected the bail application of Chakraborty and remanded him to judicial custody.
Chakraborty, a top functionary of the Burdwan Zilla Parishad and Pandabeshwar block Trinamool Congress president, was on a day's police custody yesterday.
Central Industrial Security Force personnel, in-charge of the security of the airport here, initially detained Chakraborty on January 31 for trying to board a Chennai-bound flight with an unlicensed gun and cartridges. The police later arrested him.
