Mark Strepan and Ben Tavassoli star in crime series New Blood
Actors Mark Strepan and Ben Tavassoli will head up new BBC One investigative drama, New Blood.
Created and written by best-selling author Anthony Horowitz, the seven-part series will show a unique side of modern London through the eyes of two outsiders who are both British, but not part of the establishment.
Junior investigators Stefan and Rash individually work for the Serious Fraud Office (SFO) and the police - the first time the two bodies have been portrayed on screen together.
They will come up against powerful corporations, individuals, governments and the new breed of criminals who hide behind legitimate facades.
Opposites in almost every way, what the two men do share are the same frustrations - underpaid, unappreciated and undermined.
But the duo come to understand that by combining their different skills, they make a formidable crime solving force - if they don't get themselves fired.
Strepan, taking on the role of New Blood's Stefan, played cobbler Will Whittaker in Channel 4 historical drama The Mill, while Rash will be portrayed by Tavassoli, best known as Alpha in cop series No Offence, also broadcast by Channel 4.
Speaking about his cast, Horowitz said: "When I created a hero who was Polish/British and another who was Iranian/British, I never expected that we'd actually find the real thing, but with Mark and Ben we've done exactly that. They really are the 'new blood' that the title promises and I'm confident that they're going to make a wonderfully surprising and entertaining team."
Tavassoli said: "I remember this green book knocking about at school when I was in year 7... I decided to jump on the bandwagon and pick up a copy of Stormbreaker. The only problem was I couldn't put it back down and now 15 years later I've been cast in the author's new BBC drama. Madness. It's such a privilege."
Strepan observed: "When I was seventeen I remember serving 'Alex Rider' Alex Pettyfer at a charity dinner. I was working and saving money for drama school, standing in awe of the actor who got to be a part of Anthony Horowitz's Stormbreaker. I can't wait to get started... I feel incredibly lucky to be a part of it."
BBC executive producer Matthew Read added: "It's incredibly exciting to have Anthony Horowitz back at the BBC with New Blood, and to welcome such brilliant new talent to bring this clever and bold series to life. Anthony is one of the most exceptional crime writers of our time, and to have him as the driving force behind this new drama for BBC One will undoubtedly produce genius."
Produced by Eleventh Hour Films (Safe House, Foyle's War), New Blood will be directed by Anthony Philipson (Our Girl and 24 Hours in A & E).
