DI Iain Mullan

DI Mullan is a younger man, assigned to work with Sloan after being transferred to the department due to his violent behaviour in his previous department. Hoping that Sloan will calm his behaviour, Mullan has no intention of calming down. Mullan is a bit of a vigilante himself and would very much like to work with Jason to help crack down on Mr. Philips' reign of crime and terror. 

Steven is from Greenock in Inverclyde and he runs his own business. Steven has been acting for a few years and he has a Degree in Drama from the Bay State College, MA, USA. Steven has credits on stage and in film. He is excellent as the bad tempered, aggressive Mullan.
