Brendon was arrested in October after an alleged domestic dispute at a hotel in New York, where he was accused of "grabbing his girlfriend by the throat", reported Contactmusic.
Brendon was issued a conditional discharge by City Judge James Doern, meaning he will not serve jail time in the case, if he completes drug and alcohol counselling and stays out of trouble for one year.
Brendon posted a photo of himself to his Facebook page and wrote, "It's another beautiful day on this round floating rock we call planet earth. I'm heading back to treatment today to continue #kickingdepressionintheballsack After successfully taking care of some life business. Much much love to you all.
