A pharmacist living with his parents in the suburbs of Boston was arrested on Wednesday on federal terrorism charges. He was accused of conspiring to attack people at a shopping mall in the United States, and to attack two members of the executive branch of the federal government.
The man, Tarek Mehanna, 27, was charged with conspiracy to provide material support to terrorists. The conspiracy occurred from 2001 to 2008, the acting United States attorney, Michael K. Loucks, said at a news conference in Boston Wednesday.
But prosecutors said Mr. Mehanna, born and raised in Massachusetts, was unsuccessful in acquiring weapons to carry out the attack, and was also repeatedly rejected by terrorist groups in his efforts to join them.
