Investigators are looking into whether anyone involved in the 5-year-old ring, which authorities say had a connection to organized crime in Philadelphia and southern New Jersey, bet on NHL games. Gretzky is not the main focus of the probe, the person said.

The Star-Ledger of Newark, citing unidentified law enforcement sources, first reported of a wiretap involving Gretzky in Thursday's newspapers. The newspaper also reported that Jones bet $500,000 during the investigation, including $75,000 on the Super Bowl.

Lawyers involved in the case said details of the three-month investigation should not be made public.

"I have never been involved in a case where the prosecution has engaged in such inappropriate conduct in terms of making investigators available to the press, appearing on nationally syndicated television," said Kevin Marino, a lawyer for Tocchet, who was granted an indefinite leave from the NHL on Wednesday. "It's improper, it's unwarranted and I will not tolerate it."

"We are not going to try this case in the press and we're not going to let them either," he said.

Attorneys for all three men charged in what authorities have dubbed "Operation Slapshot" said they will fight the charges.

"This case will not be a guilty plea," said Charles A. Peruto Jr., who is representing James Ulmer. Ulmer, along with Trooper James Harney, is accused of taking wagers and cuts of the bets.

The allegations have sent shock waves through the hockey world.

State investigators said they will interview more hockey players who were believed to have placed bets, in part to determine whether there was any gambling on hockey. So far, authorities say, they do not have evidence there was.

The NHL has hired Robert Cleary, a former federal prosecutor who handled the Unabomber case, to investigate.

On Thursday, Cleary said he wasn't sure how long his work might take, in part because he wants to stay out of the way of law enforcement agents who are continuing to investigate.

Hockey players are prohibited from making NHL wagers, legal or otherwise. There are no rules that forbid them from placing legal bets on other sports.
