Daniel Mays is joining the cast of the BBC’s hit police thriller Line of Duty.

The Great Fire, Mrs Biggs and Ashes to Ashes actor will appear in the third series of writer Jed Mercurio’s acclaimed BBC2 drama as Sergeant Danny Waldron, the latest potentially bent cop to come under the eagle eye of anti-corruption officers Steve Arnott (Martin Compston) and Kate Fleming (Vicky McClure).



Waldron is described as the ‘highly proficient leader of an armed response unit whose unpredictable behaviour is becoming a threat to colleagues and suspects’.



“I’m absolutely thrilled to be joining the unbelievably talented cast of Line of Duty series three. Jed Mercurio has once again delivered a thrilling and emotionally raw script which I feel incredibly honoured to be a part of,” says Danny.



The series has previously starred Lennie James and Keeley Hawes as the police officers under suspicion.
