Jason Roy reached three figures for the 12th time in ODIs before Sam Curran claimed 4 for 29 as the Tigers' run of seven straight home series victories was ended emphatically
Mirpur: England 326-7, Bangladesh 194 - England won by 132 runs
Jason Roy struck a 12th one-day international century as England ended Bangaldesh's long unbeaten home record in Mirpur.
It was a Surrey masterclass at the Shere Bangla National Stadium, with Roy's 132 helping the tourists to an imposing 326 for 7.
Sam Curran then came to the fore with the ball, taking 4 for 29 including three across his opening two overs, to claim his second-best ODI figures.
Tamim Iqbal's side were bowled out for 194 with more than five overs of the reply remaining, with Shakib Al Hasan top-scoring with 58, his 51st fifty in the format.
A dominant 132-run victory secures an unassailable 2-0 series lead ahead of the third match in Chittagong (March 6) and ends the Tigers' run of seven successive ODI series wins.

They will get a chance to claim a consolation victory on Monday before attention turns to the three-match T20I series.
England were surprisingly inserted on a fresh pitch and once Roy and Phil Salt got through the new-ball spin par of Shakib and Taijul Islam they made good progress.
Though Salt (7) was dismissed cheaply again and Dawid Malan (11) failed to add to his century in the first ODI, Roy cashed in and in between those aforementioned dismissals reached fifty in 54 deliveries with two runs through deep cover.
He and captain Jos Buttler put on a 109-run partnership for the fourth wicket, which included Roy bringing up a dozen ODI tons as he started to play more expansively.

Roy and Will Jacks (1) departed in quick succession but Buttler continued to anchor the innings, putting on a 52-run partnership with Moeen Ali.
Bangladesh were unable to exert consistent pressure and it took a moment of brilliance to end the stand when Mehidy Hasan Miraz completed a caught and bowled chance to see off Buttler (76).
Ali lashed three fours and two sixes while Curran played the perfect hand in the death overs, finishing with a 19-ball unbeaten 33.
The tourists' total was the best first-innings score at the Shere Bangla National Stadium since 2015, leaving the Tigers needing the third-highest successful chase to win and square the series.
Taskin Ahmed was once again the pick of the bowlers, taking 3 for 66, while Mehidy took 2 for 73.

Three wickets in the opening 14 balls of the chase left Bangladesh's hopes of setting up a series decider in tatters.
Curran was the chief tormentor, seducing a lazy drive from Litton Das (0) and catching edges from Najmul Hossain Shanto (0) and Mushfiqur Rahim (4).
Tamim (35) and Shakib put on 79 for the third wicket before Moeen Ali dismissed the former as James Vince took a smart catch.
Shakib followed when he became Adil Rashid's first victim, a tally he doubled when Afif Hossain (23) edged to Buttler.
Mahmudullah failed to pick Rashid and edged to Moeen, Mehidy (7) holed out to substitute Rehan Ahmed and Taskin Ahmed (21) was lazily run out as Bangladesh collapsed from 122 for 4.
Just one ball followed as the innings ended with 32 balls left unbowled when Mustafiqur Rahman edged behind to give Buttler his fourth dismissal and most credible series victory yet as the ODI skipper.
