7 Arrested In Alleged Sears Tower Plot

Seven people were arrested Thursday in connection with the early stages of a plot to attack Chicago's Sears Tower and other buildings in the U.S., including the FBI office here, a federal law enforcement official said.

As part of the raids related to the arrests, FBI agents swarmed a warehouse in Miami's Liberty City area, using a blowtorch to take off a metal door. One neighbor said the suspects had been sleeping in the warehouse while running what seemed to be a "military boot camp."

All of the alleged plotters are Muslim, and all but one is American, reports CBS News Justice producer Beverley Lumpkin. The seventh is an illegal immigrant from Haiti.

Law enforcement sources tell CBS News correspondent Jim Stewart that the alleged plotters appear to be al Qaeda-inspired, but not connected to the terror group — similar to recent arrests in Torrance, Calif., and Toledo, Ohio, where locals were inspired by, but had no direct connections to, al Qaeda.

The FBI learned of the accused plotters from a tip, which led to an undercover sting operation, reports Lumpkin. The suspects thought they were dealing with an al Qaeda operative, but were really in contact with an FBI informant.

Officials told Stewart that they didn't believe the plotters had gathered bomb-making materials or weapons yet.

Miami U.S. Attorney R. Alexander Acosta said in a statement that the investigation was an ongoing operation and that more details would be released Friday. A news conference is expected Friday morning.

"There is no imminent threat to Miami or any other area because of these operations," said Richard Kolko, spokesman for FBI headquarters in Washington. He declined further comment.

FBI Director Robert Mueller, questioned about the case during an appearance on CNN's "Larry King Live," said he couldn't offer many details because "it's an ongoing operation."

"We are conducting a number of arrests and searches" in Miami, Mueller said, which were expected to be wrapped up Friday morning.

Residents living near the warehouse said the men taken into custody described themselves as Muslims and had tried to recruit young people to join their apparently militaristic group.

The residents said FBI agents spent several hours in the neighborhood showing photos of the suspects and seeking information. They said the men, who appeared to be in their teens or 20s, had lived in the area about a year.

The men slept in the warehouse, said Tashawn Rose, 29. "They would come out late at night and exercise. It seemed like a military boot camp that they were working on there. They would come out and stand guard."

She talked to one of the men about a month ago: "They seemed brainwashed. They said they had given their lives to Allah."

Rose said the men tried to recruit her younger brother and nephew for a karate class. "It was weird," she said.

Benjamin Williams, 17, said the group had young children with them sometimes. Sometimes, he added, the men "would cover their faces. Sometimes they would wear things on their heads, like turbans."

Xavier Smith, who attends the nearby United Christian Outreach, said the men would often come by the church and ask for water.

"They were very private," said Smith, 33. "The spoke with like an accent, sort of a Jamaican accent."

Gov. Jeb Bush was briefed on the situation Thursday, according to his spokeswoman, Alia Faraj.

"We have great confidence in the federal, state and local law enforcement agencies who are committed to keeping our country safe," Faraj said.

She added that there has been greater communication between state and federal agencies since the 2001 terror attacks.

The 110-floor Sears Tower is the nation's tallest building. Security was ramped up after the Sept. 11 attacks, and the 103rd-floor skydeck was closed for about a month and a half.

The FBI's headquarters in Miami sits near a residential neighborhood just east of Interstate 95.

A huge crowd — up to 250,000 people — was expected downtown Friday for a parade to honor the NBA champion Miami Heat. Security measures consistent with such an event were in place, city officials said, and the raids were not expected to affect it.

Several terrorism investigations have had south Florida links. Several of the Sept. 11 hijackers lived and trained in the area, including ringleader Mohamed Atta, and several plots by Cuban-Americans against Fidel Castro's government have been based in Miami.

Jose Padilla, a former resident once accused of plotting to detonate a radioactive bomb in the U.S., is charged in Miami with being part of a support cell for Islamic extremists. Padilla's trial is set for this fall.
