US win four golds at World Indoors

The United States have clinched four golds on the final day of the World Indoor Athletics Championships, a fifth was removed when the men’s 4x400m relay team was stripped of gold.

This handed the title to Britain instead and it would have been six had Sanya Richards-Ross not left it late to try and overhaul Britain’s Perri Shakes-Drayton in the final leg of the women’s 4x400m relay final.
