MANHATTAN — NYPD Commissioner Raymond Kelly said Wednesday there were no specific threats against the city and its subway system following anti-terror raids in Queens this week.
The Daily News, citing unnamed sources, said more raids to seize bomb-making materials were planned. A source revealed that nine backpacks, similar to what were used in the Madrid train bombings, were found in the earlier raids.
"There are no guarantees. We live in a dangerous world," said Kelly, according to the Associated Press. "But we are doing more than anyplace else, and we're going to continue to do that."
Counterterrorism officials searched several apartments for explosives and possible links to al-Qaida operatives and questioned residents about a Colorado man who had visited the area last week, the AP reported.
Najibullah Zazi, of Denver, said Tuesday that he was pulled over by police while visiting the city last week but hasn't committed a crime. Zazi also denied he's a central figure in the terrorism investigation.
"I am an airport driver and that's all I can say," Zazi, 24, said Tuesday at his suburban Denver home, according to the AP. "This could look bad on me. It could damage my business."
Kelly would not comment on the status of the investigation.
Two law enforcement officials told the AP that a joint FBI-New York Police Department task force had put Zazi under surveillance because of the suspected links.
The task force also feared Zazi may be involved in a potential plot involving homemade hydrogen peroxide-based explosives like those cited in an intelligence warning issued Monday, said the officials, who spoke on anonymity because they were not authorized to speak about the investigation, according to the AP.
After Zazi traveled to New York City over the weekend, FBI agents and police officers armed with search warrants seeking bomb materials staged a surprise raid that rattled a neighborhood in Queens. Investigators searched three apartments and questioned residents.
