After his military service, Manbar moved to
Tel Aviv and opened up a series of businesses. His business ventures mostly ended with police investigations and indictments for crimes such as fraud, passing bad checks, and stealing checks from government employees. In 1984 he fled to the United Kingdom after being indicted for fraud, imposture, and theft, and was declared by Israel to be a fugitive from justice. He then began selling produce at the
Covent Garden market in London, but soon left Britain and entered the arms trade. He set up weapons companies in Poland and France. During his career as an arms trader, he lived in France and Switzerland before settling in Poland and setting up his headquarters in
Warsaw. Some of the weapons Manbar sold were purchased from the Polish Army. In 1994 he became a sponsor of
Hapoel Jerusalem B.C. and was barred from entering the United States. In 1997, Deputy Attorney-General for Security Affairs Dvorah Chen concluded that she could prosecute Manbar for harming the security of the state and aiding the enemy in war against Israel. Mossad officials managed to persuade a Polish businessman who served as his right-hand man to agree to testify against him. On March 27, 1997, Manbar arrived in Israel to watch Hapoel Jerusalem compete for the State Cup. Upon arrival, he was arrested by
Shin Bet and the Serious Crimes Unit of the Israel Police. His detention was initially placed under a
gag order, and was cleared for publication several weeks later. In May he was indicted and his case was brought before the
Tel Aviv District Court. ==Trial==
