Bangladesh all-rounder Shakib Al Hasan has been banned for six months for his 'severe attitude problem', the country's cricket board said.

Shakib, Bangladesh's most prominent cricketer, will also not be allowed to play in overseas competitions till the end of 2015, Bangladesh Cricket Board (BCB) president Nazmul Hassan said.

It is not easy to take such action against player like Shakib but we had to take it for the welfare of the country's cricket.

"He has a severe attitude problem, which is unprecedented in the history of Bangladesh cricket. That is affecting the total team," Hassan told reporters.

Shakib was accused of travelling to the West Indies to play in the Caribbean Premier League Twenty20 tournament without a clearance from his board and was subsequently ordered to return to Bangladesh.

The 27-year-old has played 34 Tests and 136 One-Day-Internationals and had reportedly threatened to quit playing for the country and had an altercation with coach Chandika Hathurusinghe, an allegation Shakib has denied.

"It is not easy to take such action against player like Shakib but we had to take it for the welfare of the country's cricket," the BCB chief added.

The only confirmed international fixtures for Bangladesh for the rest of 2014 is a tour of West Indies in August and September comprising three ODIs, a T20 and two Tests.

Shakib, however, won't be eligible to play domestic cricket either during this time, and will be allowed to return to action only a little over a month before the 2015 World Cup in Australia and New Zealand.
