A man presented a gun at police after a car chase in South Otago last night.

Police say the man failed to stop in Balclutha about 7.20 last night.

Police believe the 27-year-old had a firearm, so the Armed Offenders Squad was called as a precaution.

The man eventually came to a stop and got out of the vehicle, where he has presented a firearm at police.

No shots were fired, and the man was taken safely into custody.
