Nakoula Basseley Nakoula, 'Innocence of Muslims' filmmaker, questioned by US police

Egyptian protesters clash with riot police near the US embassy in Cairo on September 13, 2012. Police used tear gas as they clashed with a crowd protesting outside the US embassy in Cairo against a film mocking Islam.

Police in California are questioning Nakoula Basseley Nakoula, the man thought to be behind a controversial anti-Islam video, to determine whether he broke the terms of his probation.

Nakoula, 55, was taken into the Los Angeles County Sheriff's station for questioning early this morning, a spokesman told Reuters.

He is not under arrest and volunteered to speak to police, according to sheriff's spokesman Steve Whitmore; however, Whitmore added, Nakoula will not be returning home immediately.

Nakoula, who the Associated Press identifies as a Coptic Christian living in Cerritos, southern California, is not being questioned in connection with the content of the controversial film, "Innocence of Muslims."

Instead, federal probation officers want to establish whether he violated the conditions he agreed to after serving time for bank fraud in 2010. As part of a five-year probation order, Nakoula is banned from accessing the internet or adopting aliases without his probation officer's consent.

Nakoula, who was pictured leaving with police heavily disguised in a scarf, hat and sunglasses, has denied writing and directing the film, or posting it online.

Media investigations have found extensive links between Nakoula and "Sam Bacile," the man who originally claimed to have made the film. A law enforcement source told the AP that authorities, too, believe Bacile to be Nakoula's pseudonym.

Meanwhile Gawker has identified another man, Alan Roberts, who is believed to have directed the film under its original title, "Desert Warriors."

Gawker characterizes Roberts as a "65-year-old schlock director" who made his name in soft porn. Associates described him as "non-political" and without any apparent anti-Islam views, which suggests that he – like, apparently, several of the film's actors – may have been unaware of the movie's true purpose.
