West Yorkshire Police have released a CCTV image of two people they want to trace in connection with a robbery on taxi driver in Leeds.
The man and woman were passengers in a taxi that took them to New Briggate near to the junction with Merrion Street.
They refused to pay the fare and then attacked the 30-year-old driver.
The driver managed to get out of his vehicle but continued to be attacked in the street by the man.
He then realised that a significant amount of cash had been taken from his pocket during the attack.
The incident happened at about 3am on Sunday, April 6.
Anyone who witnessed the incident or recognises the suspects from the image is asked to contact DC 6432 Kate Hutton at Leeds District CID on 0113 385 9393 or via 101, or call Crimestoppers anonymously on 0800 555 111.
