Ricky Hatton today had his boxer's licence withdrawn by the British Boxing Board of Control.
The 31-year-old, who is to be investigated by police over allegations he snorted cocaine in a hotel room, was admitted to a rehabilitation clinic 10 days ago.
A BBBofC statement today read: "Mr Ricky Hatton MBE was legally represented at a hearing held by the stewards of the British Boxing Board of Control on Wednesday 22 September 2010 to answer charges of bringing boxing into disrepute arising out of incidents of alcohol and drug abuse by him which had been reported widely across the media.
"The board is especially concerned to keep the sport of boxing free from drugs, whether taken for recreational or performance enhancing reasons and to be vigilant in identifying and dealing with cases of alcohol abuse.
"At the hearing, the board found Ricky Hatton guilty of misconduct in that his actions and behaviour were detrimental to the interests of boxing and to the public interest and that he had brought the sport into disrepute.
"Ricky Hatton is not an active boxer and his current physical condition is such that the Board decided to withdraw his boxer's licence."
