Oh the hiding places people find for cash.

As the Justice Department argued that former U.S. government scientist Stewart Nozette should remain in jail while he awaits trial on espionage charges, juicy new details emerged about the sting operation leading to his arrest for passing top secret information to an individual he thought was an Israeli intelligence officer but really was the FBI.

Nozette was arrested at the famous Mayflower Hotel in Washington on Oct. 19 but before FBI agents put the cuffs on him, the Justice Department said that he went to the bathroom in the suite and stashed $10,000 in the toilet’s upper tank. (The money was later recovered so don’t bother booking the room.)

The money was meant as a down payment on some $2 million Nozette demanded for handing over details about a classified program that the United States had spent $1 billion to develop and deploy, according to the Justice Department.

(The Justice Department has said that Israel had no involvement in the attempted espionage.)

Earlier this year a jury convicted a former congressman, William Jefferson of Louisiana, in a corruption case that included $90,000 hidden in a freezer.
