The FBI said Thursday it has “made an arrest and is continuing to conduct authorized law enforcement activity at a residence in North Dighton, Massachusetts.

Investigators believe the guardsman, who specializes in intelligence, led the chat group where the documents were posted, according to the two people, who were not authorized to discuss an ongoing investigation publicly and spoke on condition of anonymity to The Associated Press.

They identified the guardsman as 21-year-old Jack Teixeira of Swansea, Massachusetts.
