TAMPA, Fla. (AP) — A man staying at a makeshift protest camp near the Republican National Convention has been arrested and charged with armed battery on a fellow camper.

Tampa Police say 24-year-old Dante M. Sea was charged with aggravated battery Tuesday after he hit 60-year-old Eddie Thomas and broke Thomas’ jaw.

Police say Thomas was staying in a shed in back of a military surplus store and Sea was sleeping in a tent on the same property, where protesters have set up a makeshift camp they call “Romneyville.”

Police say Sea took a piece of cardboard from Thomas’ shed and that prompted the fight.

It was not immediately clear if Sea had an attorney.

Earlier Tuesday, police broke up a scuffle between anti-GOP protesters and Kansas-based church members who often picket soldiers’ funerals.
