“I was protecting myself,” Anthony allegedly told cops “He put his hands on me.”
Anthony was sitting under another team's tent as it rained on Wednesday morning. The victim asked the 17-year-old to move, but he refused, according to the arrest report.
Karmelo Anthony then unzipped a bag, reached inside, and told Metcalf: “Touch me and see what happens,” a witness told police. Metcalf then ‘grabbed Anthony to tell him to move and Anthony pulled out … a black knife and stabbed Austin once in the chest’, police said.

Anthony ran away before he was chased down and arrested. Police are yet to press formal charges on the suspect.
