Polkowski

From Tardis Wiki, the free Doctor Who reference

Polkowski was Henry van Statten's chief aide in 2012, who warned his boss against having the US President replaced. As a result, van Statten had Polkowski fired and mind-wiped, and told the guards to leave him in an alley in a city beginning with the letter "M". He was later replaced by Diana Goddard.

It is not known what happened to him after that. (DW: Dalek)
