Martin Duko was a detective for the Metropolitan Police. He worked as a mole for Neolution, helping to cover up the implantation of bots into (sometimes unwilling) human subjects and the existence of the Leda clones.


"Unassuming and slightly nebbish, Detective Duko has the underlying angst of someone who spent their childhood getting pushed around and has since nastily clawed his way to the top. He's a perfect mole – slightly timid, a nervous air, yet efficient. Less the wolf in sheep's clothing, and more the rat in gerbil's, he’s a mid-level player in Neolution who takes orders from Evie Cho. Responsible for giving them cover from the police, Neolution’s recent technological developments has him covering up more bodies than ever, which is raising suspicions with more than just the police force."[1]


Not much is known about Detective Duko's past aside from the fact that Evie Cho has blackmailed him into doing her bidding. His main job is to keep the Neolution agenda covered from the police.[2]

Season 4

In "The Collapse of Nature", Duko is revealed to be the police union representative assigned to oversee the case involving Beth's accidental shooting of Maggie Chen.
