A US official says that an active duty Army soldier has been arrested by the FBI in Hawaii on terrorism charges.

Ikaika Erik Kang, 34, was arrested for allegedly trying to give military documents and training to ISIS, CBS News reported.

He also allegedly pledged allegiance to the terror group, CBS News said.

The US official told AP that Kang was with the 25th Infantry Division at Schofield Barracks in Honolulu.

The official was not authorized to discuss the matter publicly and spoke on condition of anonymity.

FBI spokesman Arnold Laanui told AP Monday that SWAT team special agents arrested Kang on Saturday.

FBI Special Agent in Charge Paul D. Delacourt told Fox News that the US Army and FBI had been investigating Kang for more than a year.

CBS News also said that Kang was highly decorated after deployments to Afghanistan in 2013 and Iraq in 2011.

Kang is thought to have worked alone, and is scheduled to appear in court next Monday afternoon, CBS said, citing a criminal complaint.
