Security is also a priority at clubs closer to the scene of the Sunday shooting that resulted in 50 deaths at Pulse nightclub.
At Southern Nights, another LGBT club in Orlando, management has implemented new security measures that include two police officers with their cars positioned in front of the club every night, a private security company hired to handle metal detectors, wands and pat downs, and a ban on bringing any bags into the club.
"Southern Nights has been a home to the LGBT Community for 40 years,” the club said on its Facebook post. “It is, and will continue to be a place for all people to feel comfortable and always welcome. We promise that we will do everything in our power to keep it this way.”
"In New York City, we responded to two incidents of violence where LGBT bars were targeted and references to Orlando were made," said Shelby Chestnut, director of community organizing and public advocacy at the New York City Anti-Violence Project.
She also noted that there was more than one instance where people reportedly found handwritten notes on their cars that featured "threatening language and threats targeting LGBT people."
"I think there is a lot of fear in the [LGBT] community here in NYC and around the country," de Blasio told ABC News Radio affiliate 1010 WINS earlier this week.
No specific numbers on police presence in New York have been released, but NYPD Chief of Department James O’Neill reiterated that they will be prepared for crowds at LGBT bars this weekend.
"Security is being stepped up, in particular, to areas where there is nightlife, anywhere where there are crowds, working closely with LGBT community," O'Neill said on 1010 WINS.
"I think it’s important that people have a chance to grieve, especially in public, and we will provide security for those events.”
