Ravichandran Ashwin took his 37th five-wicket haul as India beat Bangladesh by 280 runs in the first Test in Chennai.

Ashwin took 6-88 as Bangladesh were bowled out for 234 runs in their second innings on Sunday chasing an improbable 515 for victory.

Ravindra Jadeja picked up 3-58 as the spin duo consigned the Tigers to an early defeat on the morning of the fourth day.

India take a 1-0 lead in the two-match series, with the second Test starting on Friday in Kanpur.

Ashwin, who also scored his sixth Test century in the first innings, was named player of the match in his home-town Test.

Resuming at 4-158, Bangladesh put up early strong resistance.

Skipper Najmul Hossain Shanto and veteran allrounder Shakib al Hasan put on 36 as India went wicketless in the first hour.

Shakib survived a stumping chance off Jadeja after wicketkeeper Rishabh Pant couldn't grasp the ball cleanly. Otherwise the Bangladesh pair applied themselves to deny India early inroads into the lower order.

Things changed quickly in the second hour. Four balls after the drinks break, Ashwin had Shakib caught at short leg to provide the breakthrough. Shakib scored 25 off 56 balls, including three fours.

Jadeja then had Litton Das caught at slip for one, and Ashwin completed his five-wicket haul with Mehidy Hasan Miraz holing out to long-on for eight.

Shanto ran out of patience and went for a big swipe off Jadeja, falling for 82. He faced 127 balls and hit eight fours and three sixes.

Ashwin got his sixth wicket when Taskin Ahmed (five) quickly followed his captain.

Jadeja rounded out the lopsided victory in the 63rd over, bowling Hasan Mahmud for seven.

Bangladesh lost their last six wickets for 40 runs across 45 deliveries, crashing to a big defeat 10 minutes short of lunch on the fourth day.

The visitors had won the toss and opted to bowl, reducing India to 6-144 on day one. Ashwin led India's recovery with a brilliant 113, as Jadeja (86) helped add 199 runs for the seventh wicket to lift India to 376 in their first innings.

Jasprit Bumrah's 4-50 helped bowl out Bangladesh for just 149 in reply.

Centuries from Pant (109) and Shubman Gill (119 not out) helped India declare at 4-287 in their second innings.
