Until officially disbanded in 1986, the Bureau of Scientific Relations (Leshkat Kesher Madao--Lekem) collected scientific and technical intelligence abroad from both open and covert sources. Lekem was dismantled following the scandal aroused in the United States by the arrest of Jonathan Jay Pollard for espionage on ÍÍÍbehalf of Israel. Pollard, a United States naval intelligence employee in Washington, received considerable sums for delivering vast quantities of classified documents to the scientific officers (Lekem agents) at the Israeli embassy. Pollard was sentenced to life imprisonment. Although the Israeli government asserted that the operation was an unauthorized deviation from its policy of not conducting espionage against the United States, statements by the Israeli participants and by Pollard himself cast doubt on these claims.
