NEW YORK (AP) - There are no specific terror threats against New York City but the NYPD still plans a major show of force for 10th anniversary of the Sept. 11 attacks.
Police Commissioner Raymond Kelly said Wednesday that police will form a frozen zone around the World Trade Center site. They'll flood it with thousands of extra officers for the Sunday observance there with President Barack Obama and former President George W. Bush in attendance.
The beefed up security also will include hundreds of surveillance cameras trained on the site.
The commissioner said the department will deploy "quick strike reaction forces" to respond to potential threats outside lower Manhattan. The teams include officers in heavy armor, bomb squad technicians and hostage negotiators.
New Yorkers also will see extra subway patrols.
