The American flags taken from the Brooklyn Bridge last month reportedly are back in the city.
On July 22, the flags on top of the bridge were mysteriously replaced with bleached American flags.
A pair of artists from Germany later claimed responsibility for the stunt.
The Daily News says the flags were brought to police headquarters after being flown back to the U.S.
A police source tells the paper that the flags will be examined for authenticity first, then processed as evidence.
