NOTE: This story has been amended after NYPD officials denied a report, based on sources, that there was a “credible threat.”

NEW YORK – New York City police officers were reminded Tuesday in a memo to be on heightened alert ahead of the especially busy holiday season when tourists flock to the Big Apple, law enforcement sources told PIX11 News Tuesday.

Separately, a federal law enforcement source told PIX11 of a specific possible threat that could face any one of several major U.S. cities. Few details were released about the nature of the threat.

NYPD officials told PIX11 after the release of this report that there is no specific “credible threat,” as the earlier version of this report, based on sources, had stated.

Thanks for the update. If NYPD is saying no credible threat, we should probably pull this thread from breaking news.
