Polkowski

Polkowski was Henry van Statten's chief aide in 2012. He warned his boss against having the President of the United States replaced. In response, van Statten fired Polkowski and ordered him mind-wiped and left 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)
