The accused, Jamal Osborne-Adams, was charged with assault causing bodily harm following an incident at a Pizza Pizza restaurant.
The court rejected the accused's defence of self-defence and implied consent, finding him to be the aggressor throughout the altercation.
The judge found that the accused's actions were disproportionate and unreasonable, and that he intended to inflict serious bodily harm or was reckless as to whether such harm would ensue.
The accused was found guilty as charged.
