Shakib, who has a history of disciplinary problems, was found guilty of uttering abusive language after dismissing Sylhet Super Stars batsman Dilshan Munaweera while playing for his Rangpur Riders team yesterday.
He was also convicted of directing offensive and abusive language towards umpire Tanvir Ahmed in the 13th over of Sylhet's innings when an appeal against rival batsman Mushfiqur Rahim was turned down.
Shakib, who was also fined around USD 250 today, was suspended by the Bangladesh Cricket Board for six months last year for a 'severe attitude problem' although the punishment was later reduced after he apologized.
He also received a three-match ban in 2014 after making a lewd gesture towards a cameraman during a one-day international against Sri Lanka.
The 28 year old, who is the number one all-rounder in Test and ODI rankings, was also fined 30 percent of his match fee after a bust-up with Pakistani bowler Wahab Riaz during a Test match earlier this year.
