Bangladesh today handed over to Anup Chetia, leader of India's top insurgent group United Liberation Front of Asom (Ulfa), 18 years into his arrest in Dhaka for trespassing.

Chetia is wanted for murder, abductions and extortion in India.

He had sought political asylum in Bangladesh thrice in 2005, 2008 and in 2011 after Bangladesh police arrested him in December, 1997 and was subsequently handed down seven years of jail terms by two courts for cross-border intrusion, carrying fake passports and illegally keeping foreign currencies.
