Braun and Bieber's label executive James Roppo were arrested in 2009 after they allegedly failed to shut down an autograph signing at the Roosevelt Field Mall in Long Island, New York - despite pleas from police officials concerned about the large crowd.
The pair accepted a plea deal and prosecutors agreed to drop the charges so long as the singer's team reimbursed local officials an estimated $8,000 (£5,000) for the extra security. They also requested the Baby hitmaker record a special public service announcement.
And on Wednesday (10Oct12), the 18 year old distributed an anti-bullying video, putting an end to the case, according to the Associated Press.
Satisfied by the outcome, District Attorney Kathleen Rice said, "Both Idj (Island Def Jam) and Mr. Bieber's management company have learned from this incident, and since the Roosevelt Field appearance, have successfully implemented carefully executed safety plans at other venues."
