BROOKLYN, NY - White flags flowing in the sky usually mean surrender, so why was the Brooklyn Bridge in New York flying white flags?
Tuesday morning, the American flags that normally fly atop the two towers of the bridge were mysteriously replaced with white flags.
Posts on Twitter popped up early morning while many were commuting into the city.
The Brooklyn Bridge connects Brooklyn to lower Manhattan, and according to ABC News, the New York City Police Department responded to the scene and is currently investigating the security breach.
Authorities said it wasn't clear why the flags were replaced and by whom, according to ABC News.
Around 11:20 a.m., four men from the New York Police Department were seen taking the flags down and folding them into bags.
Sometime after 1 p.m., officials replaced the white flag on the Manhattan side of the bridge with an American flag.
According to ABC affiliate WABC-TV in New York, zoomed in images of the mysterious flags appear to show the American flag faintly visible under the white color.
At approximately 3:42 a.m. on Tuesday morning, footage from EarthCam of the Brooklyn Bridge shows the lights focused on the American flag on one of the towers go dark.
At a press conference, the NYPD said at approximately 3:10 a.m. July 22, a group of people crossed the bridge who are of "particular interest". At 5:30 a.m., constructions workers noticed the white flags.
Officials found two American flags that were bleached white, and aluminum pans were used as covers over the lights that were secured with zip ties.
NYPD said the individuals responsible for the incident may have experience climbing in construction or in bridgework, or may have been up on the bridge prior to the incident.
They also said the flag switch seems to not have ties to politics or terrorism, but rather to an art project or someone's attempt to make a statement.
According to the New York City Department of Transportation, the Brooklyn Bridge has more than 120,000 vehicles, 3,100 bicyclists and 4,000 pedestrians cross it every day. Prior to that time, the
