Frank Armitage

Mr Armitage was a staff member at Coal Hill School in the 2010s. He introduced Clara Oswald to Danny Pink. (TV: Into the Dalek)

During a meeting, he introduced the staff to the school's new temporary caretaker, "John Smith," who was actually the Twelfth Doctor working undercover. He was present at parents' evening, and told Mr Woods and Mrs Woods that Clara should be back in a few minutes, after she had run off with Danny. (TV: The Caretaker)

Shortly after Danny Pink's death, he informed the students and staff of the school about the death and also mentioned how their sympathy must also be expressed to Clara, who many knew had a relationship with the late maths teacher. (TV: 'Dark Water')
