(AP Photo/Eric Gay) (Newser) – A US military serviceman has been arrested after concerns were raised that a possible second attack could occur on Fort Hood, Fox News reports. Pvt. Nasser Jason Abdo, a soldier from Fort Campbell who went AWOL on July 4, was arrested near Fort Hood. Authorities won't say whether he is the person who raised their concerns; one source says two other soldiers raised concerns. A Fort Campbell spokesperson says Abdo is being investigated for child porn, while another source tells Fox News Abdo had explosives and jihadist literature in his possession when he was arrested.
