Chittagong, Oct 24: Bangladesh debutant Mohammad Ilias Sunny claimed four wickets to help restrict West Indies to 144-5 on the fourth day of the first test on Monday.
After Shahadat Hossain's early breakthrough, Sunny (4-56) had the visitors teetering in their response to Bangladesh's first innings score of 350-9 declared, with West Indies still more than 200 runs behind.
West Indies lost opener Lendl Simmons for seven and Kirk Edwards for 17 before tea and continued to struggle after the break.
Earlier in the day, Bangladesh added 105 to their day one score before declaring shortly after lunch.
Days two and three of the test were both lost due to rain.
