The United States Ambassador to Ghana Stephanie Sullivan has expressed outrage at the killing of a black man George Floyd in Minneapolis.

Solidarising with the deceased man's family and friends, the Ambassador explained that “no one is above the law.”

She added, “this incident is prompting important and necessary conversations in the United States, and servers as a reminder of the importance of confronting painful truths head-on, and of addressing the underlying conditions and existing systems that perpetuate racial injustices as we, as Americans, strive to form a more perfect union."

The 46-year-old died at the hands of a police officer who pinned him to the ground with a knee on his neck for allegedly resisting arrest on May 25, 2020.

His demise has sparked public uproar amid protests in different States across the US.

The demonstrators want an end to police brutality against the minority in the country.

One of the officers has been charged with third-degree murder following agitation after they were sacked from the police force.

Meanwhile, new charges have been levelled against all of the sacked police officers present when the African American was pinned down by their colleague.

Court documents reveal the charge against Derek Chauvin has been elevated to second-degree murder, court documents show.

The other three officers, previously uncharged, face counts of aiding and abetting murder.
