Justin Bieber escapes jail after throwing water balloons at cops

Teenage heartthrob Justin Bieber had a narrow escape in America, after police did not arrest the pop star for hitting them with a water balloon.

The 16-year-old was accused of “inappropriate behaviour” before a Maryland State Fair concert, in Baltimore, last week.

The Canadian heartthrob, who has nurtured a clean-cut image, was said to be “horsing around” with members of his staff when he threw the water-filled projectiles at two state police troopers, reports the Telegraph.

One of the balloons was said to have hit one trooper”s gun belt and burst, while the other brushed his colleague on the chest but did not burst.

According to American reports, after fleeing back to his trailer, a bodyguard who allegedly convinced police not to arrest the singing sensation saved Bieber.

No report was filed after the incident, which occurred just before the sell-out concert.

The troopers were at the concert for “crowd control”.

“Still laughing. GREAT DAY,” Bieber posted on Twitter, the micro-blogging site, later that night. It remains unclear what he was referring to.

A state police spokesman confirmed Bieber threw water balloons at two troopers while “horsing around with members of his staff”.

While describing it as “inappropriate behaviour”, he said police would take no further action. No incident report was written either, he added.
