Emergency services rushed to a Dunedin fast-food carpark this evening after a member of the public raised the alarm about three non-responsive people in a car.

Three police cars and two ambulances and another St John vehicle descended on the carpark, outside the Subway and Domino's restaurants about 5.45pm.

A police spokeswoman said "three people were found in a vehicle and weren’t responding to a concerned passerby, who called emergency services".

Two people were subsequently arrested.

A witness said a woman and a man appeared to be being interviewed by police.

Other officers were searching a silver car parked in the car park. 

No-one had been taken away in the ambulances.
