The Third Doctor was brought there by UNIT troops after collapsing in Oxley Woods from his recent regeneration. Dr Henderson thought someone in radiology was playing a prank when he and his nurse saw two hearts on the Doctor's chest X-ray, until he was similarly accused by pathologist Dr Lomax for sending him non-human blood samples. (TV: Spearhead from Space) Channing and his henchmen raided the hospital in order to kidnap the Doctor. They bludgeoned Dr Henderson and wheeled the Doctor out to their ambulance, but the Doctor escaped. (TV: Spearhead from Space)
