Donald Seagrave

On 28 February 1981, in the London Borough of Barnet, a policeman riding a bicycle stopped at a police box to make a phone call. However, the phone went dead when materialised his TARDIS around the police box. He tried to make the call again, but was dragged into the TARDIS and killed with the Tissue Compression Eliminator. His miniaturised corpse was placed in Vanessa's car. (TV: Logopolis)
