Japanese gymnastics star Kohei Uchimura was left counting the cost of his recent addiction to Pokemon Go at the Rio Olympics.

The reigning Olympic and world all-around champion became hooked on the smartphone game after touching down in Brazil to prepare for the defence of his title.

But to Uchimura's horror he was hit with a 500,000 yen ($5,000) bill after discovering that he did not have a flat rate for overseas data usage. - AFP
