But when Alan Davies was confronted with an allegedly "aggressive" homeless person after a night out in London, his mild-mannered persona was lost in a moment of Mike Tyson-like madness.



CCTV footage emerged has emerged showing Davies biting the ear of a man in an attack outside a nightclub, sinking his teeth into him for up to 13 seconds and drawing blood before two women and a man pulled him away.



The victim claimed that he was set upon after he called the actor by the name of his most famous character, Jonathan Creek.



Mr McElfatrick, 40, a former shop worker who is trying to get a hostel place, told how the 2am attack happened last week outside the Groucho Club in London's West End.



He said: "His face darkened and he almost spat the words, 'My name's Alan. You know my name - Alan. What's my name? It's Alan'.
