Three more people have been charged with violent disorder after protests in Southampton earlier this week following the murder of Henry Nowak.
Demonstrations occurred outside the police station on Tuesday evening, with 11 police officers and one dog injured.
Anger erupted after police body-worn video was released showing 18-year-old Nowak being placed in handcuffs moments before he became unconscious and subsequently died.
His killer, Vickrum Digwa, had falsely claimed he had been the victim of a racist attack, while Nowak’s repeated pleas that he had been stabbed were ignored by officers.
Connor Bishop, 24, of Oxford Street, Southampton, Reece Robinson, 21, of Soberton Road, Havant, and Noah Etherington, 18, of Rowbury Road, Havant, will appear at Southampton Magistrates’ Court on Friday morning, Hampshire Police said.
Sir Keir Starmer urged the nation to choose unity over hatred after a meeting with the family of the murdered student in which he told them he would take “whatever action is required to right the wrongs in this case”.
The prime minister said he was “profoundly humbled” to have a private discussion with the teenager’s family in Downing Street on Thursday afternoon, and said Mr Nowak “deserves a legacy that goes beyond this awful tragedy”.
The 18-year-old’s treatment by police has triggered a political row.
The Prime Minister has already urged politicians to heed the teenager’s relatives’ calls not to use the case “to cause disturbances” and branded Nigel Farage’s response “unforgivable”.
The Reform leader hit back at the criticism, insisting he condemns “all violence” and has agreed to meet Mr Nowak’s family.
Daniel Frost, 44, of Southampton, pleaded guilty on Thursday to violent disorder and possessing a dog lead with a metal carabiner as an offensive weapon following the protests.
A second man, 50-year-old Matt Styler, of Gosport, pleaded not guilty to assaulting a police officer.
Sir Keir said after the family meeting: “I was profoundly humbled to meet Henry Nowak’s family, Mark, Lucy and Katie, in Downing Street this afternoon, and to see their dignity and strength in the face of unimaginable pain.
“I was moved to learn more about Henry – his kindness, his warmth, and his love of football – and am grateful to his family.
“There is no doubt he had a bright future ahead of him, a future cruelly stolen from him in appalling circumstances.
“Henry deserves a legacy that goes beyond this awful tragedy, and I am committed to making that happen.
“I am determined that we do everything in our power to prevent other families from suffering such a devastating loss.
“There are difficult questions that need to be answered about the way the police handled Henry’s murder.
“The Independent Office for Police Conduct are investigating. We will be unflinching in taking whatever action is required to right the wrongs in this case.”
