Kiran Kaur was found guilty of assisting an offender, her son, Vickrum Digwa

Vickrum Digwa, 23, admitted to his brother, Gurpreet, that he had used a kirpan - a Sikh ceremonial knife - to stab Mr Nowak in the face and chest.

Kiran Kaur took the murder weapon used to stab defenceless student Henry Nowak to death in Southampton last year, after her son Vickrum Digwa killed him.
