LOS ANGELES, DEC. 3 -- Teamsters President Jackie Presser told of several union vice presidents' alleged organized crime ties during his 11 years as an FBI informer, a newspaper reported today.

Presser's role as an informer was described in an FBI memorandum unsealed Nov. 25 at a Cleveland court hearing for Presser and two union associates in a labor fraud case. During the period he worked as an informer, beginning in 1974, he gave the FBI tips on 69 people, according to the memo.

The memo was not dated or signed, but a source familiar with the case told the Los Angeles Times it was written in 1985 by James L. Moody, chief of the FBI's labor racketeering section, to then-FBI Director William H. Webster.

At the time, FBI officials were trying to persuade the Justice Department to reject a federal task force recommendation that Presser be indicted for placing mob-connected workers on the union payroll. Presser claims the FBI authorized the "ghost workers."

The FBI memo said: "Source is in a position to provide quality information of illegal activities of highest echelon of the International Brotherhood of Teamsters.

"In addition, source has provided information detailing the connections between the most influential families of La Costa Nostra and several international vice presidents."

The memo also said that Presser "has provided information as to how the {Teamsters} Health and Welfare Fund and the Pension Fund of the Central States has been 'used' by the various LCN families for investment in Las Vegas." A federal court in Chicago now supervises the pension fund.

The FBI agent dealing with Presser said he had authorized the payroll abuse to enable Presser to maintain his credibility among his associates. But the bureau eventually decided the agent lied to protect Presser.
