US protests live updates: Former colleague claims George Floyd and Derek Chauvin 'bumped heads'

New claims have surfaced that George Floyd and Derek Chauvin had historic tension, with the cop "afraid and intimidated" by black people.

George Floyd and the main cop charged with his murder had tension when they worked together, a former colleague claims. 

David Pinney, who worked with the men at El Nuevo Rodeo, told CBS News that Derek Chauvin an Floyd "bumped heads".

The latest revelations come as a corrections officer and a FedEx employee filmed mocking Mr Floyd's killing in a counter-protest to a Black Lives Matter march have been suspended from their jobs.

In the video, which was shared widely on social media, protesters march along a street in New Jersey chanting “George Floyd!” and “Black Lives Matter!”

As they pass a property, three men can be seen in the driveway. One kneels on the neck of another, re-enacting the death of Mr Floyd, 46, at the hands of Minneapolis police officer Chauvin, as they shout at the protesters.

The New Jersey Department of Corrections said in a statement on Tuesday one of its officers was involved in the video and had been suspended. FedEx issued a similar statement.
