NEW YORK (CBSNewYork) — The NYPD continues to be on high alert Monday following a mass shooting at a gay nightclub in Orlando that left 49 victims dead and dozens more wounded.

While authorities say there is no credible threat against New York City, residents will still see a greater police presence and a heightened sense of security.

Mayor Bill de Blasio said the city has deployed more than 500 full-time heavily armed and specially trained anti-terrorism officers.

“You’ll see them out in evidence today all over the city at key locations, well-traveled locations,” he said.

NYPD Chief of Department James O’Neill said there will also be extra security at LGBT institutions and nightlife venues.

“Anywhere there is crowds,” he told 1010 WINS. “And we’re working closely with the LGBT community to figure out exactly where we need to put our assets.”

That includes the Stonewall Inn, where heavily armed officers could be seen standing near a makeshift memorial Monday for the Orlando massacre victims.

The mayor also said extra steps are being taken to increase security during Pride Month celebrations and the parade at the end of June, WCBS 880’s Rich Lamb reported.

“As we go throughout this month, we celebrate the LGBT community, people can rest assured there will be a beefed up police presence,” he said.

De Blasio and Gov. Andrew Cuomo are both set to attend a vigil for the victims Monday night at the Stonewall Inn.
