The following is a Fox News exclusive:

At least one U.S. military serviceman has been arrested after raising concerns over another possible attack on Fort Hood, Fox News has learned exclusively.

According to an Army source, one AWOL soldier is in the custody of the Killeen Police Department near Fort Hood. He was not captured on base. According to another source, two other U.S. soldiers were also arrested earlier today after authorities recovered weapons and explosives.

Fox News has obtained the names of the three suspects, but is currently withholding that information.

Sources say the AWOL soldier in custody is from Fort Campbell, Kentucky.

It’s unclear if any possible attack was merely aspirational in nature.

On Nov. 5, 2009, Maj. Nidal Hasan, an American Army officer, carried out a shooting attack on the Fort Hood base in Texas that killed 13 people and wounded 30 others.

Hasan, a military psychiatrist, was arraigned on July 20 and is currently standing trial. His civilian lawyer withdrew from the case as it began.
