Sir Keir Starmer has paid tribute to Henry Nowak saying the 18-year-old "deserves a legacy that goes beyond this awful tragedy".
The prime minister said he was "profoundly humbled" to meet the university student's family at Downing Street on Thursday afternoon and was determined to do everything "in our power to prevent other families from suffering such a devastating loss".
There has been widespread outrage after bodycam footage showed police putting 18-year-old university student Nowak in handcuffs as he lay dying, after his killer Vickrum Digwa claimed he had been the victim of a racial attack.
Sir Keir added there were "difficult questions that need to be answered about the way the police handled Henry's murder".
Footage of the teenager's arrest showed Nowak repeatedly tell officers that he had been stabbed, with one replying: "I don't think so mate".
Digwa, 23, was jailed for life with a minimum of 21 years for murder.
After a private meeting with Nowak's father Mark Nowak, mother Lucy Ross and stepmother Katie Woodcock, Sir Keir said he was moved to learn about Henry's "kindness, his warmth, and his love of football".
"There is no doubt he had a bright future ahead of him, a future cruelly stolen from him in appalling circumstances," he said.
