A Singaporean man linked to Tokyo's bid for the 2020 Olympics was sentenced to a week in jail Tuesday for lying to officers from Singapore's anti-corruption agency who are investigating his company's shady financial transfers.

Tan Tong Han, 35, owner of the now-defunct Singapore-based consultancy firm Black Tidings, was found by the court to have lied to Corrupt Practices Investigation Bureau officers who were probing the firm's money transfers in 2015.

Tan had been charged in court in February last year at a time when media speculation was rife about his firm's alleged links to Tokyo's bid to host the 2020 Summer Olympics and to an extortion and doping scandal involving Russian athlete Liliya Shobukhova and the International Association of Athletics Federations.
