A former scientist at the United States’ space agency has been arrested on suspicion of attempting to spy for Israel, the U.S. department of Justice announced on Monday.

According to a statement by the department, the suspect, Stewart David Nozette, is a Maryland scientist who once worked in varying capacities for the Department of Energy, the Department of Defense and the National Aeronautics and Space Administration (NASA).

The department said Nozette, 52, was contacted via telephone by an individual purporting to be an Israeli intelligence officer, but who was in fact an undercover employee of the FBI (UCE).

“During that call,” the statement said, “Nozette agreed to meet with the UCE later that day at a hotel in Washington D.C. According to the affidavit, Nozette met with the UCE that day and discussed his willingness to work for Israeli intelligence.”
