A knife-wielding man has robbed a Queenstown liquor store before stealing a car to escape.
The man stole cash from a store attendant at around 6:50pm tonight, before carjacking a vehicle with another person.
The duo were followed by police cars and one person was arrested during the chase but the other managed to get away.
A police helicopter is assisting in the search for the second person.
Police advise that residents in the Mooney Road and Dalefield Road areas of Queenstown should ensure their vehicles and houses are secure, that they leave outside lights on and report any suspicious activity.
