BCB also decided not to grant an NOC to Shakib, who had also misbehaved with coach Chandika Hathurusingha, for any overseas competitions until the end of 2015.
The 27-year-old former captain had threatended to quit international cricket after Hathurusingha asked him to return to Bangladesh's training camp on August 1 for the upcoming tour of West Indies. The camp though is coinciding with Shakib's CPL campaign that runs between July 11 to August 16.
"This morning he called me. He thought that he had the NOC. He did not have any. He admitted that he misbehaved with the coach. He apologised for the misbehaviour," he added.
Apart from earlier disciplinary breaches during his international career, Shakib has had several run-ins with authority this year too.

His infamous lewd gesture towards the camera during the Bangladesh-Sri Lanka ODI series earned him a three-match ban, and currently, a BCB disciplinary committee is investigating his alleged brawl with a spectator during a Bangladesh-India game last month.
The talented left-handed batsman and left-arm spinner has represented Bangladesh in 134 ODIs and 34 Tests since his debut in 2006 and has gradually become the star player or the national team.
This is not the first time that Bangladesh players have expressed dissatisfaction over international schedule clashing with leagues in other countries. In 2013, Bangladesh's tour of Zimbabwe clashed with the IPL, which meant that Shakib and Tamim Iqbal would miss the lucrative T20 tournament.
