Boy who stabbed teacher took knife to school as part of a 'game', court hears

Taking the stand in a light blue shirt and navy trousers, the boy told the jury he and his friends had been bringing "random household objects" into school to see what they could "get away with".

When asked why he had chosen the largest knife from the knife block at his home, he said he wanted "the most impressive one to show his friends".

Asked by his defence barrister if he wanted teachers to discover it, he said "no".

The defendant was asked if he wanted to use it in a violent manner, or to deliberately cause Williams injury, but he answered "no".

Swansea Crown Court heard he had chosen to study history, and denied there being any bad feeling between him and Williams.

He also denied having any bad arguments or falling out with her.

The teenager, who was 15 at the time of the incident, said he viewed Williams as a "good" teacher, the court heard.

The trial continues.
