Naoya Tomita has left South Korea after being fined for stealing a camera during the Asian Games swimming competition ©AFP/Getty ImagesJapanese swimmer Naoya Tomita left South Korea this evening after being fined KRW₩1,000,000 (£540/$980/€745) for stealing a camera belonging to a South Korean journalist during a training session at the Asian Games here.

The case is now closed and no further action will be taken by local police, although the athlete is expected to face additional punishments once back in Japan.

The 25-year-old former world champion, who finished fourth in the 100 metres breaststroke event last week, admitted to attempting to take the camera after being confronted with compelling closed circuit television evidence proving he had done so.

He was expelled from the Japanese team as a police case was opened.

Speaking this morning, Park Dal-hwa, director of the Incheon 2014 Press Relations Bureau, revealed details of the fine, which only comes to one eighth of the reported price of the camera, which belonged to a journalist from Yonhap News Agency, the official agency of Incheon 2014.

Park also revealed Tomita had been asked to leave the Athletes' Village, but was still staying in the host city under the surveillance of the Japanese Olympic Committee (JOC).

He has since departed the country, telling reporters at the airport that he is "deeply sorry" for the trouble he has caused.

The situation has caused major embarrassment for Japan and has cast a shadow over their otherwise impressive performance in the pool here, with it hardly putting the nation in a good sporting light barely a year after Tokyo was awarded the 2020 Olympic and Paralympic Games.

Tomita is expected to face harsh punishment from the Japanese Swimming Federation, while the JOC will also consider whether to strike his records from the Games.

He is also in danger of losing financial support and sponsorship, with Descente Ltd, the Japanese manufacturer and arm of swimwear giants Arena, having already announced it is suspending his contract.

It will make a final decision over whether to terminate the contract permanently later this month.
