South Korean soccer officials say they will use lie detectors to root out match-fixing schemes.

The K-League said Monday that polygraph testing will help prevent more match-fixing scandals from erupting and better investigate those implicated in future scandals.

The K-League said it also will double the minimum yearly wage for league players to $22,670 to lessen the temptation to take bribes to fix games.

South Korean prosecutors have indicted about 70 players, gambling brokers and others in the scandal. A former K-League player who allegedly worked as a broker was found dead in an apparent suicide in May.
