One of Justin Bieber's bodyguards got busted in the most chill place on Earth -- for getting violent with a photographer and his equipment ... TMZ has learned.
The alleged tussle went down on the island of Kauai Wednesday ... when Bieber and his crew were jumping off the famous cliff on Shipwreck's Beach.
According to cops ... a 29-year-old man was snapping pics of JB & co. until one of Bieber's hired hands approached and demanded he delete all his photos.
The photog refused ... and claims the bodyguard -- Dwayne Patterson -- then got physical ... assaulting him and damaging his camera.
The alleged victim couldn't have been too hurt -- he told cops he had no injuries and refused any medical attention.
Patterson was booked for 3rd degree assault and 4th degree criminal property damage. He was released on $3,000 bail, aka ... Justin's pocket change.
It's unclear if Bieber did actually cover the bail. His reps haven't gotten back to us yet.
