New Delhi (CNN) -- India's federal police Monday arrested the chief organizer of last year's Commonwealth Games for suspected corruption.
Suresh Kalmadi was held for allegedly buying a time, scoring and result system from a Swiss company at inflated costs as head of the games organizing committee, said Dharini Mishra, spokeswoman for the Central Bureau of Investigation (CBI).
Kalmadi, she said, would be produced before a trial court Tuesday.
In February, the CBI arrested two other senior officials involved in organizing the 2010 sporting event.
Investigators took into custody Lalit Bhanot, former secretary-general of the organizing panel of the Commonwealth Games that New Delhi hosted in October last year.
Also placed under arrest was V.K. Verma, director-general of the committee.
They were taken into custody for the same suspected over-priced purchase of the Swiss equipment.
The CBI had earlier arrested four other committee executives.
Bhanot and Verma were seen as close aides of Kalmadi, she said.
A series of scandals in 2010 have put Prime Minister Manmohan Singh's government on the defensive.
Politicians, bureaucrats, officials and company executives linked to probes have denied any wrongdoing.
India's former telecom minister A. Raja, several bureaucrats and corporate officials are facing trial while in custody in connection with a mutli-billion-dollar scandal involving the suspected below-price sale of mobile-phone radiowaves or spectrum in 2008.
