Rioters who stormed the US Capitol are being turned in by their family and friends

"Even your friends and family are tipping us off. So you might want to consider turning yourself in instead of wondering when we're going to come knocking on your door--because we will."

That was the stark warning from Steven D'Antuono, the FBI's Washington field office assistant director, to the hundreds of Trump supporters who stormed the US Capitol on 6 January in an attempted insurrection that left five people, including a police officer, dead and a nation in shock.

And sure enough, some of the highest profile alleged rioters have been turned in by sons and daughters, ex-lovers, work colleagues, friends and fellow athletes – a sobering illustration of how America's bitter political divide reaches down to everyday family life.

The FBI has received at least 140,000 photos, videos and tips in the weeks since the 6 January insurrection with acting attorney general Jeffrey Rosen saying many were "notably from friends, co-workers and other acquaintances".
