Protesters clash with police amid backlash after teen's stabbing

Protesters have clashed with police in the UK after the murder of an 18-year-old. The protests were promoted by far-right and anti-immigration groups. Teenager Henry Nowak was handcuffed after being stabbed by Vickrum Digwa who falsely claimed he had been racially abused last December. On Monday, Digwa was sentenced to life in prison for his murder.
