Anup Chetia, ULFA's general secretary, was arrested by Bangladesh police in 1997.
Deported ULFA leader Anup Chetia was brought to Guwahati today by the CBI on a transit remand and produced before the court of the Chief Judicial Magistrate amid tight security.
Mr Chetia, who was incarcerated in Bangladesh for 18 years and handed over to India on November 11, was brought to Guwahati in a special aircraft and whisked away through the cargo gate of LGB Airport in Guwahati in a convoy with his vehicle led by two escort vehicles and several police vehicles behind it.
48-year-old Mr Chetia with his face covered, was taken directly from the airport to the Chief Judicial Magistrate's Court, Kamrup, a senior police official said.
His vehicle was taken inside the court's compound keeping him away from waiting journalists and the huge crowd waiting to see the insurgent leader Mr Chetia's lawyer Bijan Mahajan told waiting journalists at the court that they would apply for bail for his client.
His family members and colleagues participating in the peace talks with the government waiting at the airport, were not allowed to meet Mr Chetia.
The police official said it was not very clear whether Mr Chetia was brought directly from Delhi where he was arrested by CBI after being handed over to India or from Kolkata.
Mr Chetia's wife Monika Baruah, ULFA 'foreign secretary' Sasa Choudhury, and other pro-peace talk ULFA leaders were present in the Court premises but they were not allowed to meet him as he was whisked inside the Court.
Heavy police bandobast was made and barricades erected around the court in order to thwart attempts by people from going near Mr Chetia or raising pro-ULFA slogans as they did when ULFA chairman Arabinda Rajkhowa was produced in the court in 2009.
