From Tardis Wiki, the free Doctor Who reference

Sergeant Dennison was a police officer who worked for the Metropolitan Police Service.

On 12 April 2009, Dennison chased and tried to arrest Lady Christina de Souza, but the bus she was on fell through a wormhole. When the bus came back he attempted to arrest her again, but she escaped in the flying bus with the help of the Tenth Doctor. (TV: Planet of the Dead)
