An investigation into alleged leaks from the Prince George's County grand jury that probed the cocaine-induced death of basketball star Len Bias has revealed no evidence that warrants criminal prosecution, state officials said yesterday.

Judges in the 7th Judicial Circuit asked Maryland State Prosecutor Stephen Montanarelli to investigate possible breaches of secrecy required of grand jury proceedings after several newspaper and television stories reported accounts of witnesses' testimony.

Circuit Court Judge James Loveless said that he received the final report Thursday. "The bottom line is that there is no sufficient evidence to warrant criminal prosecution of anyone," Loveless said.

Loveless said the document consists mostly of news media accounts about the grand jury investigation and a list of people the state prosecutor interviewed. Loveless said the document would not be released.

The grand jury that investigated the June 1986 death of Bias met dozens of times over five months and heard testimony from more than 50 witnesses.

The panel indicted four men, but none of the charges was sustained.

Brian Lee Tribble, a friend of Bias', was indicted on charges of possessing and distributing cocaine and obstructing justice. Tribble was acquitted of the drug charges in June, and the other charge was dropped.

Charges of possessing cocaine and obstructing justice against Terry Long and David Gregg, two of Bias' teammates who were with him when he collapsed in his University of Maryland dormitory, had been dismissed in exchange for their testimony against Tribble.

Mark Fobbs of Northeast Washington, Tribble's former roommate, was indicted on one count of perjury, but prosecutors dropped the charge.
