ICC president Mustafa Kamal has slammed an umpiring decision in last night's match between India and Bangladesh which let Rohit Sharma off the hook.

Moments after the Indian opener was caught off a Rubel Hossain full-toss in the 40th over, umpires Aleem Dar and Ian Gould signaled no-ball but replays confirmed the ball was waist-height when contact was made and on its way down.

"From what I have seen, the umpiring was very poor," Kamal said.

"There was no quality in the umpiring. It seemed as if they had gone into the match with something in mind. I am speaking as a fan, not as the ICC president. Umpires may make mistakes. The ICC will see if this was done deliberately. Everything is on record. The ICC has to investigate and inquire the issue to see if there's anything to it."."

Bangladesh has said it will lodge an appeal while captain Mashrafe Mortaza talked to Dar briefly, but later steered away from the issue in the post-match conference.

Bangladesh were outclassed in every facet of the game, but will be cursing the way the defending champions recovered after slumping to 3-115 in the quarter-final.

"Well, everyone saw what happened in the middle. I don't want to say anything about this," Mashrafe said.

"It could have been (a more competitive match if Sharma was out then) .. it would have been great.

"I can't say anything in here, but you all have seen what's going on there."

Shane Warne questioned the call while commentating, while India legend VVS Laxman was one of many to express bewilderment on Twitter.

"Bad decision from (umpire Ian) Gould, was definitely not above the waist. Lucky break for Rohit," Laxman posted.

Mashrafe was fined 40 per cent of his match fee and given a one-game ban at any rate, having committed his second over-rate offence of the tournament.

It was a sour end to an otherwise promising tournament from Bangladesh, who defeated England then tested New Zealand in a strong finish to the pool stage.

Mashrafe took particular delight in the way his teammates adjusted to local conditions, having not toured Australia since 2008.

"It was a brilliant tournament for us," he said.

"Obviously the way we played today, it wasn't great, but most of the players ... haven't had any cricket in Australia.

"So it was a really big ask for us.
