The 61-year-old teacher was called by colleagues to help remove a pupil who had locked himself in a toilet. Martyn was told by colleagues that the child had a condition that meant he could die if he became agitated and was advised to restrain the child with a ‘guiding hold’, putting a small amount of pressure on him before moving him to a safe space.
Martyn positioned himself by the toilet door, which was removed by a colleague. As this happened, the child ran out and kicked Martyn several times in the knee.
Despite being in considerable pain, Martyn held the child as had been suggested - and as he had been taught - until the child was safe.
Since the attack, Martyn has had to have three operations on his knee and remains reliant on mobility aids. Ongoing pain disturbs his sleep and his employer, Hull City Council, later terminated his contract when he was unable to return to work.
