Police body cam captures moment woman pulls knife on ex partner

This is the moment a woman confronted her ex-partner with a knife - and was Tasered by police.

Police bodycam footage shows Sarah Purnell, 37, brandishing a blade with the red laser dot from the gun on her chest.

The officer deployed the Taser and the clip shows her falling to the ground as she cries out.

A court heard she had been arguing with her ex Adrian Bray and grabbed a knife from the kitchen, which he managed to get her to drop.
