Someone has replaced two American flags on the Brooklyn Bridge with mysterious white flags.
The white flags — international symbols of surrender — fluttered Tuesday from poles on the stone supports that hold cables above the bridge.
One of the flags, viewed via video, appeared to have faint traces of stars and stripes on it.
Police said it was not clear what time they were placed there — or by whom.
Several officers scaled the bridge and were seen lowering one of the flags around 11 a.m.
Traffic continued to inch along the bridge.
The bridge is one of the most heavily secured landmarks in the city, constantly monitored by security cameras.
The city's Department of Transportation was referring all queries to the NYPD.
Brooklyn Borough President Eric Adams came out with a statement: "If flying a white flag atop the Brooklyn Bridge is someone’s idea of a joke, I’m not laughing. The public safety of our city is of paramount importance, particularly our landmarks and bridges that are already known to be high-risk targets. We will not surrender our public safety to anyone, at any time. Political and social expression, whatever its message may be, has a place in our society, but not at the expense of others’ security. I am confident in the NYPD’s ability to investigate this matter.”
