On 31 August, 1927, Constable Henderson saw a runaway Clydesdale horse, pulling a heavy wagon. He ran alongside the horse for about 350 yards, blowing his whistle to warn the public and striking the horse in the face.
He was successful in diverting the horse and it ran into a building.
The size of the horse greatly increased the danger to the Constable. (London Gazette 1.1.28)
For his quick thinking and disregard for his own safety, Constable Henderson was awarded the King’s Police Medal for Gallantry and the Glasgow Corporation Bravery Medal.
