TOKYO – Japanese prosecutors have arrested a former senior Tokyo Olympics official over alleged bid-rigging, according to local media reports.

Tokyo prosecutors declined to comment on the reports, but the local media published photos of police raiding the home of Mr Yasuo Mori, who ran test events for the pandemic-postponed Summer Games held in 2021.

The Asahi Shimbun daily and other news outlets said Mr Mori, 55, was arrested over alleged violations of the anti-monopoly law.

Prosecutors are reportedly accusing him of rigging a string of supposedly open competitive bids and limited tender contracts for Olympic events, worth a total of 40 billion yen (S$404 million).

Mr Mori and other officials involved in the alleged rigging are said to have created their own list of candidates for the events, and bids went mostly in line with their choices. Most bids received a single tender, the Asahi reported.

Prosecutors are already investigating bribery allegations around the Games, involving claims that a former Tokyo 2020 board member took money from companies in exchange for Olympic partnership deals.

Former official Haruyuki Takahashi was arrested over the scandal, and in December, the former executive of a major clothing company admitted in court that he offered money to secure sponsorship rights, according to national broadcaster NHK.

The corruption scandal has cast a shadow over the northern city of Sapporo’s bid for the 2030 Winter Olympics.

Officials there have stopped holding promotional events for the bid and plan a nationwide poll to gauge support.

The ballooning saga is not the first time questions have been raised over impropriety around the Tokyo Games.
