Difficult to gauge what has happened but you can only go off Johnson's image and tbh, making a guess, imagine that he's just been naive and in a situation, made a big mistake or it might just be incorrect and he's, potentially, scarred for the rest of his career if he's not charged/found innocent.
I'm not a fan of naming him tbh - he was taken in for questioning, released on bail, not sure it's worth naming him for that unless he was charged.
