Bangladeshi economist and Nobel laureate Muhammad Yunus has been issued with an arrest warrant after failing to appear at a hearing over the sacking of workers at a company he heads, officials said Thursday. A judge at a court in Dhaka issued the order Wednesday as sacked workers from Grameen Communications (GC) lodged a complaint saying they were fired because they set up a trade union, court clerk M. Nuruzzaman told AFP. Yunus, who is chairman of GC, did not attend the hearing as he was abroad.
