ORLANDO, Fla. — Athletes were involved as customers of an illicit steroid distribution network that led authorities to raid two facilities and arrest four company officials, a New York prosecutor said.

Albany County District Attorney P. David Soares refused to name any steroid recipients, saying prosecutors were focused on producers and distributors.

"I understand that the involvement of athletes and celebrities makes this a sexy story, but I assure you we are not, at this point, we are not concerned with the celebrity factor," Soares said. "Our focus here is to shut down distribution channels."

Soares was in Florida on Tuesday for raids conducted by federal and state agents at two Signature Pharmacy stores. Four company officials, including a married couple who are both pharmacists, were arrested. They were charged with criminal diversion of prescription medications and prescriptions, criminal sale of a controlled substance and insurance fraud.

Soares refused to answer most questions about the case, which involves sealed indictments.

The Times Union of Albany, N.Y., first disclosed the steroid investigation in a report citing unidentified sources. The newspaper said investigators found evidence that testosterone and other performance-enhancing drugs may have been fraudulently prescribed over the Internet to current and former Major League Baseball and NFL players, college athletes, high school coaches, a former Mr. Olympia champion and another top contender in the bodybuilding competition.

The paper also said a New York investigator flew to Pittsburgh last month to interview a physician for the Pittsburgh Steelers about why he allegedly used a personal credit card to purchase roughly $150,000 in testosterone and human growth hormone in 2006.

The physician, Richard A. Rydze, told the investigator the drugs were for his private patients, the paper said, citing an unidentified person briefed on the interview.

There are no allegations Rydze violated any laws.

Steelers spokesman Dave Lockett told the AP that Rydze works for the club mostly on game days. He is listed among the seven doctors under the "medical staff" designation on the official team employment roster.

"We can't comment any further because we are still gathering information," Lockett said.

A message was left seeking comment from Rydze.
