Karate Kid Connor Mellor is celebrating after a double success at Saturday's Tang Soo Do championships in Watford. Connor, 13, fought his way through six black-belt competitors to become national under 18 Fighting Champion. On the same day, he was awarded the Stephen Ingram Memorial Award for the most outstanding under-16 competitor in Cambridgshire. Connor said: "Tang Soo Do is a great sport, both mentally and physically. I like the interaction you get with other people." Tang Soo Do is a passion shared by the whole Mellor family. Connor started the sport when he was six, accompanied by dad Lachlan (black belt) and 11-year-old sister Heather (blue belt). Mum Teresa also enjoys Tang Soo Do and all the family are "thrilled to bits" over Connor's success. Connor plans to carry on with Tang Soo Do to become 'Master Connor Mellor' - the highest rank the martial art offers and he hopes to one day become a Tang Soo Do instructor and physiotherapist.
