Prisoner (As Time Goes By)

During a police raid in 1941 in Casablanca, a man was apprehended and taken to prison.

He was placed in the same cell with Rory Williams. He correctly believed that the police was planning to kill him and to pin the murder on Rory. While the Eleventh Doctor managed to shield Rory from the consequences, the man died in the prison cell after being shot by Silurians who had infiltrated the local police. (COMIC: As Time Goes By)
