OXFORD, Miss.--Threats to use explosives to blow up buildings-one of the charges made by the feds against 19-year-old Joshua Brandon Pillault of Oxford. A news release from U.S. Attorney Felicia C. Adams says Pillault was arrested Tuesday.

It was a joint operation by the Oxford Police and the F.B.I. Joint Terrorism Task Force, assisted by the Lafayette County Sheriff's Dept. and the Bureau of Alcohol, Tobacco and Firearms.

There were few details in the news release about what the feds and local police believe Pillault did, other than a list of charges. They include: threatening to kill or injure someone with interstate communications and threatening to kill or injure someone and damage or destroy buildings by use of interstate commerce or communication.

A news release from the Oxford school district from Wednesday afternoon may clear up some of the details:

A suspect involving a threat made to Oxford High School was arrested late Monday afternoon. The administration received information about the threat Oct. 4 and took action to ensure the security of the school. The threat was not given directly to the Oxford School District. A non-resident of Mississippi received the threat from a former Oxford High student while playing an online game. The source then alerted the administration of Oxford High School. The threat of violence was made for a date in April.

Pillault is still in jail. A hearing before a federal magistrate is scheduled for Thursday in Greenville.

If he is convicted, he faces a maximum of 15 years in prison and a half million dollars in fines.

Though they did not specify what the threat may have been, the feds said in the news release that any danger has been averted.
