The all-rounder threatened to retire from Tests and one-day internationals, according to BCB president Nazmul Hasan, after being ordered by coach Chandika Hathurusingha to abort his journey to the Caribbean Premier League and attend a national training camp.
It is the latest in a string of controversies involving 27-year-old Shakib and Hasan told reporters: "He has a severe attitude problem, which is unprecedented in the history of Bangladesh cricket.
"We think that his behaviour is such that it's directly impacting the team."
Hasan also insisted Shakib had not received a No-Objection Certificate (NOC) to allow him to play in the CPL, where he is listed in the Barbados Tridents' squad.
"This morning he called me. He thought that he had the NOC. He did not have any," Hasan said.
"He admitted that he misbehaved with the coach. He apologised for the misbehaviour.
"We want to give a clear message: if it is repeated, he might be banned for life. There will be no compromise when it comes to discipline."
Shakib was previously suspended for three one-day internationals and fined 300,000 Bangladeshi taka (£2,250) after gesturing towards his crotch while on the big screen during February's second ODI against Sri Lanka.
He was also alleged to have clashed with a spectator during last month's ODI series opener against India. He admitted leaving the team dressing room during a rain break but said: " I did not raise my hand [to the spectator]. But yes, I was there."
Shakib has also played in the Indian and Bangladesh Premier League Twenty20 competitions, and had a spell in English county cricket with Worcestershire.
He has played 34 Tests, 136 ODIs and 35 T20 internationals for the Tigers and is one of their star performers, averaging higher with the bat that with his left-arm spin in all three formats.
