NYPD officials say security measures put in place for the 10th anniversary of the Sept. 11 terror attacks have been scaled back.
But they also caution that he city remains on high alert because of an unconfirmed tip that al-Qaida may be planning a bombing. They say New Yorkers will still see extra patrols in the subways and elsewhere.
Police Commissioner Raymond Kelly spoke about security Tuesday at a gathering of community leaders in advance of the Jewish holidays beginning with Rosh Hashanah on Sept. 28.
He said there were no specific threats linked to the holidays, but police still will step up security in Jewish neighborhoods and at synagogues as a precaution.
"We're making judgments literally on an hourly basis," Kelly said. "Obviously it's less than it was on the weekend, but we will continue to be vigilant at least for the near term."
New York City and Washington, D.C., tightened security last Thursday after intelligence indicated a possible threat involving car bombs, as well threats to bridges and tunnels. The information indicated that three men would travel from Pakistan to the U.S. to carry out an attack.
The threat has been described as "specific" and "credible" but not confirmed.
Several federal officials say their investigation has not generated any information to substantiate the threat information received Wednesday evening and made public Thursday.
A round-the-clock examination of flight records turned up several hundred names of interest, but interviews with those people failed to find any evidence of an actual threat.
The FBI and local police have looked for other indicators that a plot might be in the planning stages, such as large purchases of the chemicals needed to make car bombs, but no signs emerged of that either, officials say.
