Three men and a woman have been arrested following an aggravated robbery in Napier this afternoon.
The trio - aged 20, 29 and 30 - entered the Westshore Dairy, on Alfred St, about 2pm demanding money and tobacco products.
The shopkeeper was threatened with a knife and the group made off with the goods - running to a nearby street where they had a getaway driver waiting for them.
Police said a member of the public spotted the trio running towards the car and took down their details.
"He rang police and was able to give them a description and the registration of the vehicle,'' police said today.
