Former Irish skipper Trent Johnston claimed on Twitter: "Word on the street is Trott told a bunch of kids (including my son) to f*** off when they asked for an autograph."
The 30-year-old Trott, who top-scored with 69 from 105 balls in England's One-day victory, denied the charges.
Johnston, who did not play in the match because of injury, later removed his post.
"I have spoken to Jonathan Trott who assures me it did not take place and we understand Trent Johnston has now deleted the post," an England spokesman was quoted as saying by The Sun.
It was not the first instance of English cricketers getting into controversy. Former captain Kevin Pietersen vented his fury on Twitter when he was left out by England last year. He later claimed that the the feed was meant to be sent as a private message to a friend.
Tim Bresnan was also warned by the England management in 2009 after he swore on Twitter at a fan who mocked-up an image of him which made him look fat.
Trott 'foul-mouthing' kids was a misunderstanding
