AUSTRALIAN police hunting the killer of a former Oxford art gallery director have released CCTV images.

Nick Waterlow ran the Bear Lane Gallery from 1967 until it merged with the Museum of Modern Art to become Modern Art Oxford in 1972.

The 68-year-old was found dead with his daughter Chloe Waterlow, 37, at her home in the Randwick suburb of Sydney on November 9.

Mr Waterlow’s son Antony, 42, is wanted in connection with both deaths, and the CCTV images show a man resembling the suspect using a cashpoint in Randwick just before 5am on Tuesday.
