The FBI and local law enforcement personnel raided three apartments as part of a terrorism investigation on September 14, according to the Associated Press. One home was shared by five Afghans, the report said. No one was arrested and one suspect is denying earlier reports that he admitted to being involved with Al-Qaeda.

"There was nothing imminent, and they are very good now at tracking potentially dangerous actions and this was preventive," said Senator Chuck Schumer (D-N.Y.) who was informed by the FBI about the raids.

Reuters says that at least one of the suspects was under surveillance. No other details were released, but the New York Times reported that the suspects were believed to espouse the ideology of the Al-Qaeda terrorist group responsible for the attacks of 9/11.

The raids came about as a result of a probe in Denver of a suspected terrorist cell planning an attack to rival 9/11, according to the New York Daily News.

The paper also reported on September 19 that members of the suspected terrorist cell tried to rent a U-Haul truck on September 9, five days prior to the raids.

The FBI and Department of Homeland Security have told local law enforcement to look for materials that could be used in making explosives, after failing to find any such materials during the raids. The Associated Press says the memo also called on police officers to look for people with suspicious burn marks on their hands.
