A U.S. Army soldier who served in Iraq and Afghanistan and is now stationed in Hawaii has been arrested on charges of providing material support to Islamic State extremists, the Federal Bureau of Investigation said on Monday. 

Ikaika Kang, 34, an active-duty soldier assigned to the 25th Combat Aviation Brigade, 25th Infantry Division, had been under investigation by the Army and FBI for more than a year and was taken into custody on Saturday, according to an FBI statement provided to Reuters. 

According to a criminal complaint filed in U.S. District Court in Honolulu, Kang has sworn allegiance to Islamic State, also known as ISIS, the militant group that seized large swaths of territory in Syria and Iraq for a self-proclaimed caliphate. 

He also is accused of attempting to provide military documents and training to the group, the FBI said in its statement. 

Federal authorities believe that Kang, who was assigned to the Army's Schofield Barracks on the island of Oahu, was a "lone actor" who had no known associations with anyone who might pose a threat to Hawaii, the FBI said. 

He was slated to make an initial court appearance on Monday afternoon.
