Tokyo Olympics organizers said on Thursday that a policeman has tested positive for COVID-19 a day after his assignment last week at the Olympic torch relay, making him the first confirmed infection connected to the relay since it began in late March.

The policeman, who is in his 30s, was assigned to control traffic on April 17 in the town of Naoshima. He developed symptoms and tested positive the next day, local media said, adding he wore a mask and had no contact with runners.
