Police say Justin Branick was teaching a taekwondo class at Virginia's Tiger Martial Arts Academy in Bristow on Tuesday when he got mad at the boy for an unknown reason. Authorities say he grabbed the boy by the ankle and threw him over his shoulder, reports NBC News. The boy lost consciousness when he hit the ground and was treated and released from a local hospital, according to a police report. Branick was arrested after a coworker called police the day after the incident and explained what happened, the Post reports. At that point, the boy's family brought the boy back to the hospital, where police say he was treated for "serious injuries." Details weren't released. According to Inside NoVA, Branick has been released on a $5,000 bond.
