Fidel Edwards picked up five wickets in a devastating opening spell of seven overs to leave Bangladesh reeling at 86 for five in reply to West Indies' 355 at tea on day two of the second test in Dhaka.
The hosts had no answer to Edwards' extra pace and bounce on a supposedly low and slow track and were reduced to 59-5 before former captain Shakib Al Hasan provided some resistance.
Shakib (30) and Naeem Islam (six) were the unbeaten batsmen at the crease when tea was taken.
All-rounder Shakib earlier took five wickets to help Bangladesh wrap up the West Indies innings after Kirk Edwards made his second century in his third test.
Tamim Iqbal, who was reprimanded by the match referee for his verbal tirade against Marlon Samuels on Saturday, triggered the collapse when he fell to a catch at short leg, unable to fend off a short ball.
Shahriar Nafees was dismissed in similar fashion as the diminutive paceman also sent back captain Mushfiqur Rahim lbw off the very next ball.
Shakib kept out a deadly yorker on the hat-trick ball but the damage continued from the other end with Imrul Kayes giving a catch to Kraigg Brathwaite for Fidel Edwards's fifth wicket.
Earlier, Kirk Edwards (121) and Marlon Samuels (48) added 87 for the sixth wicket before Shakib led Bangladesh's fightback with 5-63, his eighth five-wicket haul in tests.
Nasir Hossain ended the stand with a sharp return catch after Samuels played a fluent knock, which included seven boundaries.
Edwards, unbeaten on 71 overnight, brought up his century with a boundary off Nasir and was out lbw to Shakib after hitting 14 fours and two sixes.
