Two large mysterious white flags over the Brooklyn Bridge in New York City appeared.
White flags, which are symbols of surrender, flew from poles on the stone supports atop the famed bridge that connects Brooklyn and Manhattan over the East River.
The New York City Police Department responded to the scene and is investigating the matter.
It is unclear who placed them there and why, authorities said.
A video captured by Earthcam shows the flagpole platforms, when they go from flying the American Flag to having the lights turned off:
The flags, which appeared to be American flags that had been painted white, were in the same place where U.S. flags typically fly.
Police said they will review surveillance video to determine who placed the flags there, according to WABC.
“This has nothing to do with a film shoot,” confirmed Dean McCann, Executive Director of NYC’s Mayor’s Office of Film, Theatre and Broadcasting.
