A former police officer is being investigated on suspicion of leaking information to one of the suspects in a police investigation of Foreign Minister Avigdor Lieberman.

A few months ago, the national fraud squad asked the Justice Ministry department in charge of investigating police misconduct to begin an urgent investigation of Superintendent Rami Cohen Gvura, then an officer in the fraud squad, on suspicion of leaking information related to the Lieberman case. The Lieberman investigation is thought to have been one the most compartmentalized in the unit, which specializes in white-collar crime.

A source familiar with the Justice Ministry probe said that once Cohen Gvura came under suspicion, he decided to leave the police department. The ministry is expected to decide soon whether there is enough evidence to indict the former officer.

The Justice Ministry said it is "conducting an investigation into a former police officer on suspicion of leaking information from an investigation. The investigation has not yet concluded, so we cannot divulge additional details."

Cohen Gvura dealt with several very high-profile cases as a fraud squad officer. Within the past year, he testified at the trial of former Prime Minister Ehud Olmert regarding how the police obtained material from the Industry, Trade and Labor Ministry's computers, including the appointment books kept by Olmert's then-office manager, Shula Zaken.

"Aside from Ehud Olmert's case, I've assisted many cases on this matter - computer work, obtaining [information] from computers," he told the Jerusalem District Court during his testimony.

The Lieberman investigation, which began in 2006, dealt with suspicions that the minister had been running a transatlantic network of businesses alongside his various government jobs. A few months ago, Attorney General Yehuda Weinstein announced that he intended to indict Lieberman, pending a hearing.

Cohen Gvura served most recently as a detective in the fraud squad's economic division. Before that, he was a detective in its cyber-crime division. He has a bachelor's degree in math and computer science and is a computer engineer by profession.

News of the investigation into the former officer's conduct shocked those who knew him.

"He's a quiet, serious guy," one source who knows him well told Haaretz. "I was stunned when I learned he had left the [fraud] squad."

A police spokesman said: "With no connection to the substance of your question, we do not comment on personal staff issues."

Cohen Gvura declined to comment.
