West Indies wrapped up a 296-run victory inside four days in the second match against Bangladesh in St Lucia to secure their first Test series victory in 18 months.
The hosts declared on 269 for four as soon as Shivnarine Chanderpaul notched his 30th Test century and, set a mammoth 487 to win, Bangladesh made a decent start before yet another batting collapse saw them all out for 192, extending their winless sequence to six matches in this format.
The comprehensive victory, helped first by Chanderpaul's unbeaten 101 and then Sulieman Benn's 5-72, ensured Denesh Ramdin's side secured their first Test series triumph since the 2-0 win over Zimbabwe in March last year.
Resuming on 208 for four, the Windies immediately set about scoring quick runs and Jermaine Blackwood moved to a half-century.
A couple through square-leg brought Chanderpaul his ton and, after he leapt for joy, sunk to his knees and kissed the Beausejour Stadium turf, Ramdin motioned for he and Blackwood, with 66 not out, to return to the pavilion.
Bangladesh openers Tamim Iqbal and Shamsur Rahman added 47 for the opening wicket until the latter tried to hook Jerome Taylor and succeeded only in finding Kemar Roach at deep square-leg.
The tourists were two down three overs later with just one run added when, on nought, Anamul Haque edged a turning Benn delivery behind.
After a brief rain delay following the tea interval, Tamim moved to his 16th Test fifty and Mominul Haque, earlier dropped by Darren Bravo, then reached the milestone.
But Bangladesh then undid all their hard work in the morning and early afternoon by capitulating from the relatively healthy position of 158 for two to 192 all out.
Tamim top-edged playing across the line to Benn to depart for 64, Mahmudullah was trapped lbw by Shannon Gabriel without scoring, Mominul, on 56, picked out midwicket and Nasir Hossain was pinned lbw to leave Bangladesh 167 for six.
Taijul Islam then offered Benn a simple return catch for his sixth Test five-wicket haul, before Mushfiqur Rahim, Robiul Islam and Shafiul Islam fell soon after as Bangladesh surrendered meekly.
