According to a state police spokesperson, while the hair-flipping wonder boy, 16, was "horsing around with members of his staff" outside his trailer, he chucked water balloons at two troopers, reports Baltimore's WBAL-TV. One balloon hit a trooper's gun belt before it burst, and the other balloon sideswiped a trooper on the chest.
The troopers were monitoring crowd control at the concert, which was sold-out. Police did not file an incident report and will take no further action, said the spokesperson about Bieber's "inappropriate behavior."
