British International Olympic Committee member Adam Pengilly has been sent home from the Pyeongchang Winter Olympics following an altercation with a security guard.
The IOC announced Pengilly's departure on Thursday after the incident, reportedly outside a hotel.
An IOC spokesperson said: "The IOC wishes to apologise for the behaviour of one of its members, and feels extremely sorry for the incident caused by Mr Adam Pengilly.
"Following an interview with the IOC Ethics and Compliance officer he will leave the Olympic Games and South Korea with immediate effect.
"We would like to once again thank all the authorities and the police who are doing an excellent job and deserve all our thanks.
"Mr Pengilly has expressed his apologies to the security man involved. His mandate as an IOC member will expire on February 25."
Former skeleton slider Pengilly, who competed in two Olympics, has been a member of the IOC Athletes' Commission since 2010.
He has been an outspoken critic of the IOC's approach to Russia.
