Federal authorities question man who may be anti-Muslim filmmaker

Last Updated 7:04 a.m. ET

(CBS News) LOS ANGELES - The filmmaker who may be behind the anti-Islamic movie that sparked widespread protests in the Muslim world against the U.S., some of which turned violent, was escorted from his Cerritos, Calif., home shortly after midnight local time Saturday by Los Angeles County Sheriff's deputies.

CBS station KCBS video showed Nakoula Basseley Nakoula, 55, with a hat on and towel around his face, and wearing winter jacket in the L.A. summer heat, being escorted from the suburban L.A. house.

Nakoula, a self-described Coptic Christian, is thought to be the filmmaker behind "Innocence of Muslims."

The Sheriff's Department told KCBS it is assisting federal authorities with an investigation they're conducting, for questioning on a possible violation of his parole..

"Nobody is arrested. Nobody is detained. Nobody is in custody," said a, L.A. Sheriff's Dept. spokesperson.

Reuters reports deputies say Nakoula left his home voluntarily.

Nakoula was convicted in 2010 of bank fraud, and was not allowed to use the Internet.

KCBS correspondent Carter Evans told "CBS This Morning" the probe centers around possible probation violations by Nakoula stemming from the making of the movie, as he was not allowed to use computers or access the Internet as part of his probation.

If Nakoula is indeed behind "Innocence of Muslims," Evans noted, how did the trailer of that film get on the Internet?

After an Arab language version of the trailer was posted, a wave of protests - some violent - erupted across the Islamic world.

An attack on the U.S. consulate in Benghazi, Libya, shortly after the video was posted resulted in the deaths of four Americans, including Ambassador to Libya Chris Stevens.

The four bodies were returned to the U.S. Friday.

More protests following Friday prayers erupted in cities around the world. At least five people died in clashes between demonstrators and security forces.
