Police praised an Oamaru resident who reported a heavily intoxicated drink-driver yesterday.
The member of the public was concerned at seeing a 41-year-old Te Anau man allegedly get into his truck and drive off.
Oamaru community constable Bruce Dow pulled over the driver on Severn St at 9.20am. The man blew a staggering 1604mcg, and was instantly banned from driving for 28 days. The adult limit is 400mcg.
Mr Dow said the driver admitted to drinking a bottle-and-a-half of Jack Daniels with a relative in an all-night drinking session.
The veteran police officer said the level was the highest he had seen and described the driver as a "potential killer".
