Four cars have been parked at Beijing Capital International Airport for at least six months, including an Audi that has been there three years.

The airport authority said it reported the four cases to police, hoping to find the owners, Beijing Youth Daily reported on Wednesday.

A micro-blogger posted recently that he found a car still parked in Terminal 3 after he first saw it in May 2011.

An airport official said it would not remove the cars as car owners have the right to park there.

The report said the parking fee for three years could be 55,000 yuan ($8,970).
