Detective Inspector (Logopolis)
From Tardis Wiki, the free Doctor Who reference
This Detective Inspector found Vanessa's corpse. It had been shrunk by the Master.
When he saw the Fourth Doctor and Adric, the Detective Inspector accused them of the murder. His officers and he arrested the Doctor and were about to take him to the Police station when Adric tricked them, letting the Doctor escape to the TARDIS. When he got the key to the TARDIS, he found it had taken off without him knowing. (DW: Logopolis)
