As he sits in his prison cell, Stuart Briggs may be wondering why jiu-jitsu is known as the “gentle art”.
The thug, 35, randomly attacked 16-year-old student Alex Williams, not knowing he is an expert in the martial art, and was slammed to the ground.
He was jailed for 20 months this week for biting Alex, who has now set up self-defence classes for under-12s who might be targeted by a bully too.
