Donald Seagrave

On 28 February 1981, in the London Borough of Barnet, Constable Donald Seagrave (PROSE: Logopolis) was riding a bicycle and stopped at a police box to make a telephone call.

Biography
While Seagrave was on the phone, the line went dead when materialised his TARDIS around the police box.

He tried to make the call again, but was dragged into the police box/Master's TARDIS and killed with the Tissue Compression Eliminator. Segrave's miniaturised corpse was placed in Vanessa's car, alongside the shrunken body of Vanessa herself; both were later discovered by a plain-clothes detective inspector and two uniformed officers.
