SD


Shay Doyle is a former soldier and police officer who was one of the UK's chosen few Level 1 undercover operatives.

He was a decorated detective, leading covert operations and tackling high-profile murder cases. Shay's central role in some of the most daring police operations of modern times was unparalleled, but leading a double life, constantly on edge, eventually took its toll. Shay is now a mental health advocate working alonside professionals and organisations to tackle the stigma attached to mental health in high-risk and high-pressure roles. He is also a passionate activist against gun, gang and knife crime.
