Oh, and don't worry, Justin's mum wasn't hurt in New Zealand. She posted her own message online to say she was OK and thanked her son's fans for their support.
Justin also got his hat back. In a later message on his Twitter page, he said: "Sorry...U can't hold me ransom. I got my hat back. no hugs. no thank u's. just glad they did the right thing. I don't condone thievery!! haha"
