this is not david yip
David Yip is best remembered for his gritty portrayal of a chinese detective in London's Chinatown in the 1981 series 'The Chinese Detective'. I have also heard that he played 'Veldan' in the Doctor Who story 'Destiny of the Daleks', and he also played 'Editor #1' in The Professionals episode Discovered in a Graveyard.
Or so I am told.
