Adis Medunjanin, a Bosnian immigrant, met voluntarily with investigators for 14 hours, said Robert Gottlieb, a New York lawyer representing him, reports CBS News Investigative Unit producer Pat Milton. Zarein Ahmedzay, a 24-year-old New York City cab driver, also was interviewed by the FBI, said his brother, Nazir Ahmedzay.
Both men's photos were among four shown to Ahmad Wais Afzali, an imam at a Queens mosque accused of tipping off Najibullah Zazi that New York Police Department detectives were searching for him. Ron Kuby, a New York lawyer representing the imam, confirmed that detectives showed Afzali photos of Medunjanin and Ahmedzay along with Zazi's.
Naiz Kahn, a high school friend of Zazi's who allowed him to stay in his Queens apartment last month when prosecutors say Zazi was preparing his attack, said he also has been questioned by the FBI. But his photo was not among those shown to the imam, said Kuby. The imam did not know the identity of the man in the fourth photograph, Kuby said.
Neither man is tied to the terror plot prosecutors claim Zazi was pursuing, said Gottlieb and Ahmedzay's brother.
Prosecutors and the FBI declined to comment.
Law enforcement sources tell Milton investigators are closely looking for a crack in the door of these alleged associates to try to determine if any of them can be tied to a crime.
No immediate arrests are anticipated, Milton reports. It is believed that no one is currently being sought overseas. No one is believed to have fled the country. "They are all still here," a law enforcement source told Milton.
Gottlieb said Medunjanin has met with investigators, who have not been in contact with him since the interview weeks ago. After that meeting, Gottlieb said Medunjanin hired him.
Medunjanin agreed to meet with investigators after they raided his apartment last month, Gottlieb said. "He had nothing to hide," Gottlieb said.
FBI agents seized computers and cell phones from the apartment, but returned them later, he said.
"There's no indication of any evidence that he was involved in a crime," he said. "There would be no basis for charging him with anything."
Gottlieb said that Medunjanin is an American Citizen with a graduate degree in economics who works in a building management business. Medunjanin's parents are American citizens as well. "He and his family are living a nightmare," Gottlieb said.
Investigators had an interest in Medunjanin before the raid, Gottlieb said, without elaborating. "The reasons are not any evidence of wrongdoing or crimes," he said.
Gottlieb did not confirm that his client's photo was among those shown to the imam.
Medunjanin grew up in the same area of Flushing, Queens, as Zazi, Gottlieb said, declining to elaborate.
Zarein Ahmedzay, the other man identified by the Queens imam in the photos with Zazi, has no connection to Zazi's case, other than being interviewed by the FBI, and was not involved in a plot, said Nazir Ahmedzay, his brother. "No, never," Nazir Ahmedzay said during a brief interview outside his apartment.
Zarein Ahmedzay, a U.S. citizen, lives with his brother in a Flushing apartment in the same neighborhood as the one Zazi's family shared before moving to Denver in January.
Nazir Ahmedzay said his younger brother has never been to Colorado. He also said Zazi has never been to their apartment.
Afzali, a reliable police source in the past, has pleaded not guilty to lying to federal agents who asked him about his phone calls to Zazi after detectives showed him the photographs. Kuby said Afzali was only doing what police asked him to do.
Zazi, 24, who left New York earlier this year to take a job driving an airport shuttle in Denver, is the only person charged in an international terror investigation described by Attorney General Eric Holder as one of the most significant plots uncovered in this country since 9/11. Zazi, who's being held without bond, has pleaded not guilty to conspiring to use weapons of mass destruction.
Prosecutors have said Zazi and others they have not identified received explosives training at an al Qaeda camp in Pakistan. U.S. intelligence and senior administration officials have said they became aware of Zazi's connection to a possible plot in late August. They said he was recruited and trained by al Qaeda, and he had contact with a senior al Qaeda operative.
Investigators are still hunting for additional players and expect to make more arrests. Officials say Zazi's suspected accomplices are under surveillance and are no longer a threat because the plot was thoroughly disrupted.
Federal authorities accuse Najibullah Zazi, of Denver, of trying to make a homemade explosive using ingredients from beauty supply stores in the Denver area.
Authorities say the 24-year-old, who allegedly received terror training at an al Qaeda camp in Pakistan, was plotting an attack in New York City on Sept. 11.
He is being held without bond in New York. He has pleaded not guilty to a charge of conspiring to detonate explosives in the United States.
The U.S. Attorney's office in Denver announced Thursday that a grand jury had returned an indictment against Mohammed Zazi, 53 (left), for allegedly making a false statement in a matter involving terrorism.
Zazi was arrested last month on that charge pending a grand jury indictment.
He is free on $50,000 bail and under electronic monitoring. He is scheduled to appear in federal court on the charge Friday afternoon.
The indictment alleges Mohammed Zazi lied to the FBI when asked if he had spoken to anyone about his son on the phone and whether he was in any trouble with authorities.
Prosecutors say that Mohammed Zazi did speak to someone on or about Sept. 11 about his son and that at one point, Mohammed Zazi warned his son that he should hire an attorney.
"What has happened? What have you guys done?" Mohammed Zazi asked his son, according to a criminal complaint.
If convicted of lying to authorities, Mohammed Zazi faces a maximum of 8 years in prison.
