Polokov is the android that lasered the senior bounty hunter, Dave. He works for the city as a trash collector. Polokov was mimicking an anthead-a special. That's how he got Dave. He lasered Dave while he was giving him the Voigt Kampff test. Polokov is a Nexus-6, an advanced android model. When Rick meets him, Polokov is playing the role of a W.P.O. cop named Sandor Kdalyi, who is supposed to help Rick catch the androids. Rick realises the trick just on time and retires Polokov right before he strangles Rick.
