Vangel Dhimitri talked to media this week about the incident on Paltara Way where he was called to pick up a man and take him to the airport about 2.15am on September 27.
Warwick Detectives said the man was waiting with a suitcase, and while Mr Dhimitri loaded it into the vehicle, he turned off the engine and used a knife to threaten the driver.
The man, who was described as being fair-skinned, about 30 years old, 180cm tall and of medium build, stole cash and ran off towards Stockholm Road.
‘Dob him in, ring Crime Stoppers, because he will harm someone,’ Mr Dhimitri said.
Anyone with information regarding this incident, or who recognises the man can call Crime Stoppers on 1800 333 000.
