The International Olympic Committee has set up a disciplinary commission to investigate the incident involving Ryan Lochte and three of his U.S. swimming teammates at a Rio de Janeiro gas station.
IOC spokesman Mark Adams tells The Associated Press the panel was formed Friday to look into the behavior of Lochte, Gunnar Bentz, Jack Conger, and Jimmy Feigen.
Adams had no other immediate details.
IOC disciplinary commissions have the power to issue sanctions.
Lochte, a 12-time Olympic medalist, apologized Friday for his behavior surrounding the early-morning incident. He reiterated his view that a stranger pointed a gun at him and demanded money to let him leave the station.
Lochte had called it a gunpoint robbery; Brazilian police said he and the three other swimmers vandalized a bathroom while intoxicated and were confronted by armed security guards.
