FREEPORT — Investigators say an Iranian Muslim man who came to Maine as a refugee in 2009 was fighting for the Islamic State group when he was killed last year in Lebanon.

The Portland Press Herald reports that details about 38-year-old Adnan Fazeli were in newly unsealed court documents filed in federal court in Portland.

The newspaper reports Fazeli, who was most recently a Freeport resident, became radicalized while living in Maine.

Fazeli came under FBI investigation for his connection to Islamic State shortly after leaving his job at a Portland auto dealer and flying to Turkey in August 2013. He never came back.

Fazeli died in battle in January 2015 as a member of an Islamic State force of about 150. The group was turned away by the Lebanese army.
