The alleged perp "sneaked into the area with the teen through a small gate." Doesn't appear to be a crime there, though I imagine authorities are continuing to question the alleged target that could be more difficult because of his disability.
Of course, the background of the alleged perp and the fact that he attempted to run will be considered by them, too.
What people surmise isn't cause for arrest.
As it stands now, the guy has his name in the paper; he also suffered a broken ankle.
