Hey guys, a friend of mine went to this house party. He stole the hosts phone, but the next day he gave it back. Apparently there were camera's, so they know for sure it was him. Apparently, after he gave the phone back, they said the phone wasn't working properly anymore, and they were ready to call the cops on him. He says he didn't break it.

I would like to know what can happen to him. I know they might let it go, but if they don't, what are the things the police can do to him.

Thank you !
