Tokyo prosecutors indicted Dentsu and five other firms, as well as seven individuals, on Tuesday over alleged bid-rigging on contracts for the Tokyo 2020 Olympics.

The move came after the Fair Trade Commission filed criminal complaints against them earlier in the day.

The indictment marks the latest development in months of investigations into alleged corruption in the planning and sponsorship of the Tokyo Olympic and Paralympic Games, held in 2021 after a pandemic-driven postponement.
