Martin Compston (better know as D.I Arnott in TV mega-hit, Line of Duty) is a Scottish actor (with a Scottish accent which we still can't get over) and former professional footballer.
He's best know for playing Anti-Corruption Unit Detective Inspector Steve Arnott in the BBC drama Line of Duty - for which he uses a very convincing English accent - but has also played parts including: Liam in Ken Loach's Sweet Sixteen, Paul Ferris in The Wee Man, Ewan Brodie in Monarch of the Glen and Dan Docherty in The Nest.
He's currently on our screens in Our House on ITV. But he hasn't always been an actor. He grew up in Greenock in Scotland and his first career was in sport, playing football professionally for his local home professional team, Greenock Morton.
