British police launched a huge manhunt Wednesday for a man believed to be armed with a crossbow and potentially other weapons after three women were killed in a house northwest of London. The BBC said the women killed were the family of well-known radio racing commentator John Hunt.

Hertfordshire Police said Kyle Clifford, 26, was being sought over the suspected triple murder, which involved a crossbow and potentially other unnamed weapons. The public were urged not to approach Clifford if they see him.
