The Olympic Village is located on Harumi Island in Tokyo
The organizers of Tokyo 2020 are investigating athletes who drink alcohol in a park in the Olympic Village.
Athletes are only allowed to consume alcohol in their rooms and alone as a precaution against Covid-19.
Police visited the Olympic Village scene, but the athletes were not named.
“We are looking into the matter. We will take appropriate steps based on our findings,” said Toshiro Muto, the head of the Games Organizing Committee.
Muto highlighted the incident after it became known on Saturday that two Georgian silver medalists had won were asked to leave the Olympic Games for a sightseeing tour in Tokyo.
He also said that six people involved in the games had their accreditation withdrawn for violating coronavirus rules.
Japan has extended the state of emergency in the host city after a surge in cases.
