A 19-year-old Dunedin student got more than he bargained for when he went to the central police station this morning.

About 3am he went to report that he had been assaulted, but he appeared extremely intoxicated and police were suspicious about how he had travelled to the station.

They discovered he had driven a motorised scooter, which he had allegedly stolen from a crash site in Stuart Street just hours earlier.

The student was also found to be on active charges of driving while intoxicated, driving while disqualified and for boy racer activity.

He now faces additional charges of drink-driving, unlawfully taking the scooter, and driving while suspended.

He's due to appear in court on Tuesday.
