Panorama reveals harrowing footage and other evidence of domestic violence incidents that now account for a third of all recorded assaults with injury in England and Wales. Filmed by police response teams equipped with body-worn video cameras, this new style of evidence gathering is helping to bring perpetrators to justice. But years of coercive control and terror often lie behind the violence. Panorama hears from wives, mothers and children who have also endured non-violent domestic abuse, which is now likely to be made a criminal offence in its own right.
