Harry MacReid

Commissioner Harry MacReid was a senior officer with MAID. MacReid rose quickly to the rank; he was a constable during the Kyren invasion of 1963, but within two weeks had been named commissioner.

A man of Scottish origins, MacReid was friendly with Constable Will Doyle. Several encounters with hostile aliens led him to be distrustful of extraterrestrial beings. When the Kyren attack came, MacReid was separated from the rest of the MAID defenders, and made his way to the Albion Hospital, where he encountered the Doctor, Emily Whitaker, and Verity Roberts.

When the hospital was breached, MacReid (along with the Doctor and Emily) was taken by Kyren forces for experimentation. They were rescued by Constable Doyle, and taken to the Totter's Lane junkyard. There, he was exposed to both a TARDIS and Emily's Korina form for the first time.
