On January 8, 2012, Zubair, an honours final year student of English at JU, was stabbed to death by members of an opposing faction of the ruling Awami League’s student front over their previous animosity and political rage.
On February 23, 2014, Ashik, Sohan, Akram and Ishtiaq Mehbub Arup, who was, too, sentenced to life imprisonment by the lower court, escaped from the courtroom soon after it had rejected their bail pleas and sent them to jail.
Sources said most of the fugitive convicts had fled to Malaysia and are active on different social media sites such as Facebook and Instagram.
