India bowled Bangladesh out for 324 on the fifth and final day to win the first Test by 188 runs and take a 1-0 lead in the two-match series here on Sunday.
Bangladesh added 52 runs in 11.2 overs in the morning session and lost four wickets in the process after resuming the day on 272 for six while chasing an improbable 513 for a win.
It was a matter of completing formalities for India after Axar Patel grabbed three wickets towards the end of the fourth day to push the visitors closer to victory.
The second and final Test starts on December 22 in Mirpur.
Brief Scores: India: 404 and 258/2.
Bangladesh: 150 and 324 all out in 113.2 overs (Zakir Hasan 100, Shakib Al Hasan 84; Axar Patel 4/77, Kuldeep Yadav 3/73).
Wrist-spinner Kuldeep Yadav registered his career-best match figures as India quickly wrapped up Bangladesh's second innings for a comprehensive 188-run win in the opening Test, here Sunday.
Needing four wickets to pocket the win, India finished the job in 11.2 overs, bowling the hosts out for 324 after the hosts began at overnight score of 276 for six.
Left-arm wrist spinner Kuldeep scalped two of the remaining four batters while Mohammed Siraj and Axar Patel took one wicket each.
Kuldeep, who cherished an impressive five-wicket haul in the first innings, added three more wickets in the second Bangladesh innings to finish with match figures of 8 for 113.
"I love bowling with Kookaburra balls, it gives me better grip and control, compared to the SG ball," said Kuldeep after the win. "If I were not playing cricket, it would have been very challenging but I have played a lot of white-ball matches. I have played IPL and with red ball India A matched, so my rhythm was set. I could bowl with aggressive approach and in this rhythm, you need to make extra effort and it takes a toll on body," he said.
"I like playing all formats of cricket for India, nothing matches that pride. When I don't play I keep training so that the confidence remains intact in matched but I stay relaxed," he added.
Kuldeep was ably supported by left-arm spinner Patel, who finished with figures of 4 for 77 in the second innings.
