A motorist allegedly threw a diving bottle through the windscreen of a police car after being told his vehicle would be impounded.
The Napier man was stopped during a routine police vehicle check yesterday morning.
Acting Sergeant Shane Rowland said the man was found to be driving without a valid licence when he was pulled over on Ellison Rd about 9.30am.
"On hearing that the vehicle he was driving was to be impounded, he took a dive bottle out of his car," Mr Rowland said.
The driver allegedly threatened to damage property with the dive bottle.
