A Massachusetts man has been arrested on federal terrorism-related charges on suspicion of planning attacks inside and outside the United States.
A person familiar with the investigation who spoke on condition of anonymity says the man was arrested early Wednesday. The person was not authorized to divulge details of the investigation.
The person says the man is from the Boston suburb of Sudbury and had two co-conspirators.
Tarek Mehanna, of Sudbury, was arrested in November 2008 on suspicion of lying to authorities about the whereabouts of a man who trained with al-Qaida members with the goal of overthrowing the Somali government.
Mehanna pleaded not guilty and was released on bail. Officials would not immediately say Wednesday whether the man arrested was him.
