Feds Take Denver Man and Father into Custody in Alleged al Qaeda Plot

Federal agents arrested Najibullah Zazi and his 53-year-old father, Wali Mohammed Zazi, in connection with an investigation into an alleged al Qaeda plot at their home shortly before 10pm Saturday night in Aurora, Colorado. They are charged with "making false statements to federal agents in an ongoing terror investigation," which carries up to eight years in prison.

At 9:30pm, six black SUV's with red and blue flashing lights rushed into a suburban housing complex, and a group of FBI agents climbed three flights to Zazi's apartment.

The officers remained inside for about five minutes. They first brought out Zazi's father, in handcuffs, escorted by two agents, and placed him in a waiting vehicle. Next, Najibullah Zazi , in handcuffs, surrounded by agents, was brought down, placed in a second car and the caravan sped off.

In New York, FBI agents also arrested Ahmad Wais Afzali, 37, on the same charge. He is a legal permanent resident of Afghanistan and lives in Flushing, NY.

All three men are scheduled to appear in court Monday - the Zazis in federal court in Colorado and Afzali in an Eastern District of New York courtroom.

Federal prosecutors are expected to bring criminal charges against at least three men in an alleged al Qaeda plot to attack New York, including 24-year old Najibullah Zazi. Zazi's arrival in New York last week triggered a series of raids by the FBI and New York city police intended to disrupt what authorities described as "a real deal" attempt to attack targets in New York.

Zazi, who initially denied any ties to al Qaeda, later admitted connections to the terror group and told FBI interrogators he had received explos vies training at a terror camp in Pakistan.

Other men associated with Zazi, one in Denver and the other in New York, may also face prosecution, authorities told ABCNews.com.

"The FBI has not give us any notice," said Wendy Aiello, a spokeswoman for Zazi's lawyer, Arthur Folsom.

Late Saturday night, Aiello said of Najibullah and Muhommed Zazi's arrests, "Their attorney, Arthur Folsom, is with them at FBI offices in Denver, Colorado. Specific charges are unavailable at this time."

A computer belonging to Zazi showed he had researched baseball and football stadiums and sites used in the recent Fashion Week event in New York City, law enforcement officials tell ABCNews.com.

Zazi had been scheduled to spend a fourth day today being questioned by the FBI but his lawyer canceled the session.

"He has taken the day to consult with his client," Aiello saif.

Zazi is not in custody, she said.

While officials say they do not know the targets of the alleged plot, the contents of Zazi's computer are considered a valuable insight into what he might have been planning.

After first denying any ties to al Qaeda, Zazi has now admitted certain ties developed during trips to Pakistan, law enforcement officials told ABCNews.com.

The officials said text messages sent by Zazi suggest the plot was nearing the attack phase. One message said the "wedding cake is ready," which authorities say may have been code to indicate the attack was ready. Al Qaeda operatives have frequently used references to weddings to disguise planned terror attacks.
