Nahid Rana claimed his first Test five-wicket haul as the West Indies were bundled out for 146 in reply to Bangladesh's first-innings total of 164 just after lunch on the third day of the second and final Test at Sabina Park on Monday.
Starting the day at 70 for one, the home side were swiftly undermined by the 22-year-old fast bowler who finished with figures of five for 61, adding four more victims to the dismissal of Mikyle Louis the previous evening.
Rana was well supported by fellow seamer Hasan Mahmud (2 for 19) in Jamaica.
Keacy Carty top-scored with 40 while captain Kraigg Brathwaite, the first wicket of the day when he was caught in the gully off Rana, contributed 39.
West Indies lead the series 1-0 after winning the first Test in Antigua by 201 runs.
