Fitness fanatic saves police officer's life using martial arts technique he learnt on Youtube

A 5ft 6ins labourer has told how he saved the life of a police officer being strangled in the street - by using a martial arts move he learnt on YouTube.

Joshua-Jon Hill, 26, was on a bus travelling home from the gym when he saw a thug grappling with a policeman on the street with his hands around the officer's neck.

Brave Joshua-Jon ordered the bus driver to stop and leapt to the officer's aid during the attack in Leicester at around 9pm on October 16.

The fitness fanatic got the 6ft 4ins yob in a headlock before putting his knee on a pressure point in the spine, forcing him to release his grip.
