The US intelligence leaks suspect was concerned about getting caught transcribing documents at work, so he started taking them home, a member of his online chat group told the FBI, according to court documents.
Air National Guard member Jack Teixeira, 21, is suspected of posting the leaks. Investigators did not name the group member the FBI interviewed in the affidavit.
Teixeira, "began taking the documents to his residence and photographing them" due to his concern about getting caught, the group member told investigators, according to the court document.
The leaks included photos of crumpled documents lying on top of magazines and surrounded by other random objects, such as zip-close bags and Gorilla Glue, CNN has previously reported.
The documents looked as if they had been hastily folded up and shoved into a pocket before being removed from a secure location, a source familiar with these kinds of documents told CNN.
