"Just horsing around with members of his staff"

Police: Bieber Hit Md. Troopers With Water Balloons

Pop Star Accused Of 'Inappropriate Behavior'

BALTIMORE -- It seems teen sensation Justin Bieber had a bit of a run-in with Maryland state troopers before his sold-out concert Sunday at the Maryland State Fair.

Thousands of fans attended Sunday night's concert at the Timonium Fairgrounds.

A state police spokesperson said Bieber, while "horsing around with members of his staff," threw water balloons at two troopers, the 11 News I-Team's Jayne Miller reported.

One of the balloons hit a trooper's gun belt and burst, and the other brushed a trooper on the chest but didn't burst, Miller reported.

It happened outside a trailer Bieber was using before the concert. The troopers were there for crowd control.
