Newly released court documents say an Iraqi-born man living in California used a social media account associated with the Islamic State group to plot a return to Syria.

Aws Mohammed Younis Al-Jayab was indicted in Sacramento Thursday on one federal charge that he lied to investigators about traveling to Syria to fight against the government there.

Documents made public Friday show the investigation of the 23-year-old apparently began with information from the search of a Virginia-based Facebook account in April 2014.

That was shortly after Al-Jayab returned to the United States from his second stint fighting in Syria, according to the search warrant affidavit.

He was arrested last week and remains jailed.

Prosecutors and his attorney say there is no indication he intended harm within the United States.
