Man says he was informant for FBI in Orange County

Ayloush said he was "100% sure" that Monteilh was the informant in question and expressed anger and disappointment that the FBI would infiltrate mosques. He accused officials of trying to entrap innocent Muslims, noting that Monteilh has been convicted of grand theft and forgery in the past. He said Muslims had worked hard to develop a partnership with the FBI -- and had been assured by J. Steven Tidwell, then assistant director in charge of the Los Angeles field office, at an Irvine forum in 2006 that their mosques were not being monitored. Now, Ayloush said, he has doubts about future relations with the FBI.

"This is religious profiling at its worst," Ayloush said about the FBI operation.

The Afghanistan-born Niazi, 34, was arrested last week and is scheduled to be arraigned next month on suspicion of perjury, naturalization fraud, misuse of a passport obtained by fraud and making a false statement to a federal agency. Niazi, who has lived in the United States since 1998 and earned citizenship five years ago, is related by marriage to Amin al-Haq, an Afghan militant who fought the Soviet occupation of the 1980s with a U.S.-backed Islamic resistance force that now is branded an Al Qaeda affiliate. Niazi is accused of failing to disclose those ties during his application for citizenship.

Niazi asserted after his arrest last week that he is an innocent man who is being retaliated against by the FBI for refusing to become an informant.

In Tuesday's bail hearing, Ropel asserted that Niazi was a danger to the community who should be held without bail. But prosecutors offered no testimony regarding the specific plots Monteilh says he told the FBI that he discussed with Niazi, allegedly involving attacks on Orange County shopping centers, military installations and court buildings. Nor was there any testimony about other mosque members allegedly having been involved in those or other terrorist activities, as Monteilh maintains was the case.

Ayloush said he had received numerous complaints from Muslims in 2007 that Monteilh was aggressively promoting terrorist plots and trying to recruit others to join him. Citing such behavior and saying that it made members of the mosque feel threatened, the Islamic Center of Irvine won a temporary restraining order in June 2007 that barred Monteilh from the mosque.
