Vandals avoided cops and managed to plant flags at the top of the Brooklyn Bridge. The incident raised fears of terrorism. 
Tuesday’s white-flag incident wasn’t the first terror scare on the Brooklyn Bridge.
In May 2013, cops raced to the bridge when an abandoned SUV was found parked in the middle of the span. Traffic was halted for an hour so the bomb squad could check out the vehicle and allow it to be towed away.
The biggest terror plot against the bridge was revealed in April 2011. Terror mastermind Khalid Sheikh Mohammed had given underling Iyman Faris orders to cut away at the thinner suspension cables to the Brooklyn Bridge, aiming to destroy it.
The plot was hatched before 9/11, but in 2011, then-NYPD Commish Raymond Kelly called the scheme “doable” before more security measures were put in place.
