A man has been arrested for alleged trademark infringement after being found to be in possession of fake commemorative medals for the Tokyo 2020 Olympic and Paralympic Games.
The medals that will be awarded during next year's Winter Olympic Games in Pyeongchang have officially been unveiled during special events in Seoul and New York City.
Medals awarded during last year's Olympic and Paralympic Games in Rio de Janeiro have begun to disintegrate and need repairing.
Tokyo 2020 organisers have today called on the Japanese public to donate old electronic devices so the metal can be used in medals for the Olympic and Paralympic Games.
Researchers and university students have launched a petition which asks Tokyo 2020 organisers to use recycled metal to produce the medals that will be awarded to athletes at the Olympics and Paralympics.
Medals at the Tokyo 2020 Olympics could be made out of recycled metals as part of an environmental drive by organisers.
