A man brandishing a hammer stormed the bedroom of a young couple in the early hours of Sunday morning.
The man then drove away at high speed and crashed into a tree stump, leaving damaged parts behind.
Police believe the parts belong to a dark Toyota Rav4.
The car will have moderate damage to its front left bumper.
The man was covering his face with a bandana when he broke into the Napier house about 5.30am.
