The FBI has made an arrest in connection to a recent leak of classified documents that revealed sensitive details about the war in Ukraine and other US intelligence matters, apprehending a young Massachusetts Air National Guard member on Thursday, April 13th. 21-year-old Jack Teixeira, who holds the rank of airman first class, allegedly shared the files to a Discord server primarily dedicated to Minecraft. According to The Washington Post, he first transcribed the documents manually when he started sharing them late last year before posting photos of the classified materials themselves.  

The Justice Department has arrested Jack Douglas Teixeira in connection with an investigation into “alleged unauthorized removal, retention, and transmission of classified national defense information,” Attorney General Merrick Garland said in a statement issued by the Justice Department. As NBC News notes, public military records show that Texeira was assigned as a cyber transport systems journeyman at Otis Air National Guard Base on Cape Cod. 

Based on the The Post’s investigation, Teixeira, who used the pseudonym “OG” on the Discord server, claimed he partly worked at a secure facility where phones and cameras are prohibited. That’s reportedly the reason why he originally copied the documents by hand before the lack of interaction on the server prompted him to post photographs of the original documents. Some of the photos contained random items and furniture that may have given investigators a clue on his identity. 

Despite the sensitive information contained in the documents, the suspect apparently did not intend to be a whistleblower — according to The New York Times, members of “Thug Shaker Central,” the original Discord server, say the documents were never intended to be shared outside of their small group. Eventually, though, they were shared to other Discord servers before finding their way to Telegram channels, 4chan and other social media platforms.   

The documents Teixeira had leaked included large amounts of information regarding the Russian invasion of Ukraine, including detailed battlefield conditions and missile strike maps for the latter. They also reportedly showed how Egypt had planned to sell Russia tens of thousands of rockets and how Russia approached Turkey, a NATO ally, to buy weapons. In addition, the documents apparently contained information showing how the US spies on its foreign allies.  

Discord previously said that it was cooperating with authorities regarding their investigation on the leak. As for Teixeira, he will make his initial appearance in the US District Court for Massachusetts.
