The brother of the black man who was shot dead by US police this month called the video of the murder “the most horrific” he’s ever seen.
Michigan police this week released footage of a police officer shooting 26-year-old Patrick Lyoya in the head after a scuffle over a taser.
Mr Lyoya’s family, Congolese refugees, spoke to the media on Thursday and demanded that the agent’s name be released.
State police are investigating the incident that sparked protests.

Dozens of protesters rallied outside the Grand Rapids Police Department (GRPD) on Wednesday to demand that the name of the police officer involved be released.
Authorities said the officer will not be identified unless criminal charges are filed against him.
Originally from the Democratic Republic of the Congo, Mr. Lyoya has lived in Grand Rapids for about five years, according to the office of civil rights attorney Benjamin Crump, who represents the Lyoya family.
Mr Crump said of Thursday’s shooting: “There’s no way to try to spin it or justify it.
He asked that the officer be fired and charged.
“What you see in this video is the excessive, unnecessary and unjustifiable use of deadly force. You see a police officer turning a simple traffic stop into a deadly execution,” he said.
GRPD chief Eric Winstrom called the shooting a “tragedy”.
What do the videos show?
On Wednesday, the GRPD released footage of the incident from a police body cam, a police unit dash cam, a cellphone and a home surveillance system.
One of the videos shows the police officer stopping Mr. Lyoya’s vehicle just after 08:00 local time (12:00 GMT) on April 4.
The officer decided to stop the car for false registration, according to authorities quoted by CNN.
Mr. Lyoya gets out of the car, but the policeman asks him to get back in.
Mr. Lyoya appears confused, stays out of the vehicle and asks what he did. The officer asks if he speaks English and Mr. Lyoya replies “yes”.
Mr. Lyoya is then asked again and again whether he has a residence permit and, after a short conversation, flees from the officer.
The two then fight on the ground and the cop pulls out his taser, which the two use to fight. The officer tells Mr. Lyoya to drop the electric baton.
During that altercation, the officer accidentally turned off his body camera, according to police.
However, footage taken from Mr Lyoya’s passenger’s mobile phone was also released, apparently showing the officer shooting Mr Lyoya in the back of the head.
The police officer is currently on administrative leave to await the outcome of the investigation.
During a Wednesday briefing, Grand Rapids Police Chief Eric Winstrom said, “Based on my review of the video, the taser was used twice. The taser made no contact.”
“And Mr. Lyoya was shot in the head. However, that is the only information I have,” he said, calling the incident a “tragedy.”
Mr Crump, who represents the Lyoya family, called for the officer to be fired and charged.
He tweeted that the videos showed the police officer shooting at the unarmed Mr. Lyoya “while he was lying on the ground facing the officer!”
“Patrick never used force against this officer, although the officer used force against him on several occasions,” added Mr. Crump.
Response from the US Ambassador to the Democratic Republic of the Congo
In a Twitter thread posted to his official account on Thursday, US Ambassador to the Democratic Republic of Congo Mike “Nzita” Hammer expressed his condolences over Mr Lyoya’s “tragic death”.
“This horrific incident is being investigated [que] Accountability and justice can follow. As [Secrétaire d’État des États-Unis Anthony] Blinken recently said that the universal nature of human rights also means we must hold ourselves accountable to the same standards. We have recognized from day one of this administration that we have challenges here in the United States. We take our responsibility to address these shortcomings seriously, and we know what matters: with citizens and communities, openly, in a transparent way – without trying to pretend the problems don’t exist or to hide them under the rug sweep,” he wrote.
