Deepak Chahar produced a record-breaking six-wicket haul adorned by a hat-trick as India overcame a stellar knock from Mohammad Naim to seal the T20I series 2-1.
Chahar's bowling heroics came late in the innings as he finished with astonishing figures of 6 for 7, overtaking the previous-best spell recorded in the format by Ajantha Mendis (6 for 8).
The right-arm paceman, making just his seventh T20 international appearance for India, dismissed Shafiul Islam, Mustafizur Rahman and Aminul Islam off successive deliveries in a hat-trick spread across two overs to become the first Indian to register this feat in 20-over cricket.
It was not all doom and gloom for Bangladesh, who were bolstered by a splendid batting effort from 20-year-old Naim as he made 81 off 49 deliveries before being dismissed amidst a passage of play that saw the chasing side lose four wickets for nine runs.
Left-handed opener Naim put on 98 runs for the third wicket alongside Mohammad Mithun - the only other batsman in the Bangladesh innings to get to double figures.
Naim's explosive knock featured 10 boundaries and two sixes as his crisp strokeplay blunted the Indian bowling lineup that looked clueless for most of the chase.
Chahar returned to bowl the 13th over after snaffling two wickets upfront to have Mithun miscue a slog towards long-off providing his side an opening into Bangladesh's middle order.
All-rounder Shivam Dube then accounted for the wickets of dangerous Naim, veteran Mushfiqur Rahim and young Afif Hossain - the latter two for golden ducks - to seriously dent the tourists' resistance.
Chahar capped off India's resurgence by wiping off the tail in an exquisite display of swing bowling helping his side to a remarkable 30-run triumph.
India did not have a decent start with the bat after losing both their openers inside the Powerplay to the guile of pacer Shaiful Islam.
KL Rahul and Shreyas Iyer then revived the hosts' innings with a vital 59-run stand as the two individuals amassed half-centuries.
Rahul's wicket was followed by another flop show from Rishabh Pant but Iyer held one end firmly and launched five sixes during his enterprising 33-ball 62.
Manish Pandey hit three boundaries in the death overs to lift India to an imposing 174-5 making sure the momentum was with his team.
In spite of the dew factor expected to spoil India's attempts at defending the challenging score, Chahar and company fought back the externalities to sustain India's dominant home season.
