A US navy nuclear engineer with access to military secrets has been charged with trying to pass information about the design of American nuclear-powered submarines to someone he thought was a representative of a foreign government but who turned out to be an undercover FBI agent, the Justice Department has said.
n a criminal complaint detailing espionage-related charges against Jonathan Toebbe, the government said he had sold information for nearly the past year to a contact he believed represented a foreign power. That country was not named in the court documents.
Toebbe, 42, was arrested in West Virginia on Saturday together with his 45-year-old wife, Diana, after he had placed a removable memory card at a prearranged “dead drop” in Jefferson County, according to the department.
The FBI said the scheme began in April 2020 when Toebbe – a US government employee since 2012 – sent a package of navy documents to a foreign government and said he was interested in selling operations manuals, performance reports and other sensitive information.
Authorities said he also provided instructions for how to continue the secret relationship, with a letter that said: “I apologise for this poor translation into your language. Please forward this letter to your military intelligence agency. I believe this information will be of great value to your nation. This is not a hoax.”
The FBI’s legal office in the foreign country received the package, which had a return address of Pittsburgh, last December. That led to an undercover operation over several months in which an agent posing as a representative of the foreign government offered to pay thousands of dollars in cryptocurrency for the information Toebbe was offering.
The FBI said that in June the undercover agent sent 10,000 US dollars (£7.3 million) in cryptocurrency to Toebbe, describing it as a “sign of good faith and trust”.
Authorities said that as part of the operation, the FBI observed that Toebbe arrived on multiple occasions at agreed-upon locations for the exchange, concealing an SD card between two slices of bread on a half-of-a-peanut butter sandwich in one instance and in a chewing gum package in another.
The complaint alleges violations of the Atomic Energy Act, which makes it a crime to disclose information about atomic weapons or nuclear materials with the intent of harming the United States.
The Toebbes, from Annapolis, Maryland, are due in court on Tuesday in Martinsburg, West Virginia.
