Detective Inspector (Logopolis)

A plain-clothes detective inspector and two uniformed police officers found the shrunken corpses of Tegan Jovanka's Aunt Vanessa and a policeman in Vanessa's car — which had a flat tyre and was in a lay-by on the Barnet Bypass — on 28 February 1981.

Biography
The detective inspector had never seen anything like it, and the Fourth Doctor realized Vanessa and the policeman had been killed by using his Tissue Compression Eliminator.

When the detective inspector accused the Doctor, he accused him of the murder. He and his officers arrested the Doctor and were about to take him to the police station when Adric tricked them, letting the Doctor escape to the TARDIS, which had materialized around the police box which was situated in the lay-by.

When the detective inspector used the police box's key to open the door, he found the TARDIS had taken off without him knowing, leaving behind an ordinary police box containing traffic cones and warning signs. (TV: Logopolis)
