Bangladesh, who were set an improbable victory target of 508 runs, were shot out for 278 soon after lunch on the fifth day at the Sher-e-Bangla stadium. Bishoo, the Guyanese bowler who turns 26 on Sunday, returned with career-best figures in only his seventh Test and skipper Darren Sammy chipped in with 2-19 to rout the hosts.

The emphatic win after the drawn first match in Chittagong will provide a massive morale-booster for Sammy's men, who begin a three-Test series in India on Sunday. It was the first series win away from home for the West Indies since November 2003, when they beat Zimbabwe 1-0. Their last Test win abroad was against South Africa in Port Elizabeth in December, 2007.
