Bangladesh national and former Awami League leader Nur Hossain, prime accused in the sensational 7-murder case, was deported to Dhaka by India.
Police said Indian authorities handed him over to a Bangladesh Police team at the Benapole border.
The reciprocal gesture comes a day after Dhaka handed over ULFA leader Anup Chetia to New Delhi.
Earlier reacting to Anup Chetia’s return to India, Bangladesh Home Minister Asaduzaman Khan had clarified that Bangladesh expects Nur to be returned not in exchange but on account of good relations between the two countries.
