Car egging?

I hope this doesn't come off over dramatic, I'm just curious though. My fiancé had his car egged last night and the light pole in front of their house was hit repeatedly with a bat. They have cameras in front of their house and should be able to identify whoever did it. My fiancé is washing off his car right now and said that the egg has eaten some of the paint on his car. If they are able to identify the person, what happens next? Will they get arrested, fined, sued? And for what? If it helps, we live in Florida. Thanks in advance!
