NAIROBI, Kenya - Kenyan police say they want to investigate "all athletics training camps in the country" for doping after arresting a well-known Italian agent on suspicion that he conspired to provide banned substances to runners.

Kenya's anti-narcotics police unit says in court documents in the case against agent Federico Rosa that they want to interview "affected parties" at the country's famous high-altitude training bases.

The investigation comes less than a month before the Olympics, where Kenya's athletes were likely to be under heavy scrutiny anyway following a series of doping scandals. This investigation could throw some Kenyan athletes' Olympic preparations into turmoil.

Rosa was released on $3,000 bail Friday having been arrested this week. One of his top clients, three-time 1,500-meter world champion Asbel Kiprop, was in court as an onlooker.
