A crewmember was stationed onboard the prison station which held Davros.

When the Daleks invaded the station, he and Osborn went to try and kill Davros, but the Daleks had pumped poisonous gas into the station. The crewmember began to choke on the gas, which prompted Osborn to shoot and kill him. (TV: Resurrection of the Daleks)
