TURIN, Italy — Italian investigators paid a return visit to the Austrian ski team targeted in anti-doping raids at the Winter Olympics, prompting the head of the nation's ski federation to call angrily for authorities to justify the continuing scrutiny with evidence.

Austrian ski officials said investigators came to some of the team's private apartments Monday evening, two days after a police sweep reportedly yielded syringes and other material that was still being analyzed for possible doping violations.

Police said an Italian prosecutor inspected a private home in the mountain hamlet of Pragelato Monday night where banned Austrian ski coach Walter Mayer had been staying before he bolted the Olympics and surfaced in Austria.

Turin paramilitary police spokesman Roberto Cicatelli stressed that the inspection was not a second raid, and no evidence was collected.

"Nothing has been taken away, no one was checked because there was nobody there," Cicatelli told The Associated Press.

Raimund Fabi, press coordinator for Austria's Olympic committee, said investigators had not returned to the same ski team housing in Pragelato and nearby San Sicario where Saturday's raids were conducted.

"It was only a talk with more people from the Austrian Ski Federation, and it was at different accommodations," Fabi told the AP.

It wasn't immediately clear whether Fabi was referring to the prosecutor's inspection of Mayer's housing, or a separate visit elsewhere.

Austria's ski federation president, Peter Schroecksnadel, said he did not know the purpose of the investigators' visit — but was incensed that they had returned at all.

"I think they're going too far with the whole thing," Schroecksnadel said. "This is not sport ... We won't live with this. We can't have our guys going through this. It's no longer about sport, it's just about rumors."

Against the backdrop of the most stringent drug controls in Winter Games history, a series of raids were conducted late Saturday, the first-ever doping sweep by police on athletes at the Olympics. Six skiers and four biathletes were taken for drug screens by the International Olympic Committee.

Authorities also reportedly seized 100 syringes and other material, but no test results were announced as of Tuesday morning. International Olympic Committee spokeswoman Giselle Davies said the IOC would only make a detailed statement if something incriminating was found.

"When there's a violation, the IOC communicates on that," Davies said. She did say, however, that in this case the IOC would give an indication of when the testing process was completed.

Schroecksnadel challenged the authorities behind the investigation to justify their methods, suggesting that they returned to the Austrians' living quarters only because the first sweep had not yielded any evidence of doping.

"Why are the results not here from the guys who were tested?," he said. "They find nothing, this is why they're still breaking into the apartments, because they haven't found anything. They keep coming back. I don't agree with the way they're doing things with this, even if it is the state."

The investigation was touched off when World Anti-Doping Agency officers learned that Austrian ski coach Walter Mayer, banned from the Olympics for links to blood doping in 2002 in Salt Lake City, was with the team at the Turin Games. WADA told the IOC of Mayer's presence, which in turn tipped off Italian police.

The night after the raids, authorities said Mayer crashed his car into a police blockade 15 miles inside Austria's border with Italy, some 250 miles from Turin. Schroecksnadel said police took him to a psychiatric facility, where he was staying because it was feared he might commit suicide.

Mayer appeared in an Austrian court Tuesday to face charges related to his bizarre flight from the Winter Games. He pleaded guilty to charges of civil disorder, assault and damage to property, court spokesman Norbert Jenny told The Associated Press.

Italian authorities said they were investigating Mayer for a possible violation of Italy's stringent anti-doping laws, but were not seeking his arrest.

Austrian ski officials said they have severed ties with Mayer. Though he had been in Italy coaching the team in a private capacity, IOC medical commission chief Arne Ljungqvist said his presence — while not breaking any rules — had violated the "spirit" of his Olympic ban.
