U.S. law enforcement in D.C., N.Y. and L.A. go on high alert in wake of Paris attacks

Deadly attacks in Paris on Friday night have prompted American law enforcement officials to take precautions in U.S. cities, although authorities say no credible threat has been detected in the United States.

The New York, Washington, D.C., and Los Angeles police departments all reported deploying additional patrols to high-profile locations across their cities Friday night.

Scores were killed in at least seven separate but coordinated attacks that spanned the French capital and included gunfire aimed at a cafe in an area of the city known for its vibrant nightlife, the slaying of dozens of hostages inside the Bataclan nightclub, and two explosions near the Stade de France stadium north of Paris during a France-Germany soccer match.

The New York Police Department deployed critical response vehicles to sensitive locations in the city, including the French Embassy and other diplomatic posts, according to a local NBC affiliate.

Likewise the Metropolitan Police Department in Washington, D.C., “deployed additional law enforcement resources to French-owned sites and other high-profile locations,” D.C. Mayor Muriel Bowser said. A D.C. police car was seen parked outside the French Embassy in the District.

U.S. Capitol Police also reported stepping up patrols around the Capitol complex.

Federal officials cautioned that no credible threat against targets in the United States has been detected, and local agencies emphasized that their increased police presence was out of an abundance of caution.

Both the Department of Homeland Security and the Federal Bureau of Investigation are monitoring the situation in Paris, where at least 100 were reported dead.

“At this time, there is no specific or credible threat to the United States,” said a DHS official speaking on background. “We will not hesitate to adjust our security posture, as appropriate, to protect the American people.”

Other police departments across the country were also monitoring the situation in Paris, including the Boston Police Department which issued a statement saying it was “encouraging officers to remain vigilant as they conduct their patrols.”
