Guwahati, Nov 7 (PTI) Two top ULFA leaders, who surrendered before the BSF, have been brought to the city even as the banned outfit called a 12-hour Assam Bandh on Monday demanding their unconditional release.

The two self-styled ULFA Foreign secretary Sashadhar Choudhury and self-styled Finance Secretary Chitraban Hazarika surrendered at Gokulnagar along the Indo-Bangla border on the intervening night of November 4 and 5.

The two were brought here in a special aircraft from Tripura and kept last night in the police special branch headquarters in Kahilipara after their arrest, police said.

The ULFA leaders were likely to be produced in the Chief Judicial Magistrate Court Kamrup today.

Demanding the unconditional release of the two underground leaders, ULFA chairman Arabanda Rajkhowa in an e-mail to the media today called for a bandh on Monday and demanded that the two leaders be produced before the media.
