The chief organiser of last year's Commonwealth Games in the Indian capital, Delhi, has been arrested on corruption charges.
Suresh Kalmadi was removed from the post in January and has been under investigation over accusations of corruption. He denies any wrongdoing.
The build-up to the Games was marred by disclosures of sleaze, incompetence and missed construction deadlines.
In February, organising committee secretary-general Lalit Bhanot and another top official, V K Verma, were arrested and accused of financial irregularities linked to the Games.
The Central Bureau of Investigation said Mr Kalmadi was arrested for conspiracy to cause favour to a company in Switzerland while procuring timers and scoring equipment for the Games'' at inflated prices.
Other charges reportedly relate to contracts at a 2009 event in London which marked the start of a baton race across Commonwealth countries.
Mr Kalmadi is expected to appear in court on Tuesday.
