CCTV footage shows the moment murderer Steve Williams was arrested by police after he had stabbed his girlfriend more than 40 times.
The 31-year-old, from Tenby, Pembrokeshire, was found guilty at Swansea Crown Court of killing Joanna Hall, 35, in June last year.
Ms Hall, who had just started seeing Williams, identified the chef as her killer from her hospital bed.
She died three weeks later.
