The attack took place during a summer holiday dance class for children at the Hart Centre in Southport.
Rudakubana, who was 17 at the time, also stabbed eight other children along with yoga teacher Leanne Lucas, who was instructing the class, and businessman John Hayes, who was one of the first people on the scene.
A peaceful vigil was held in the town the next day, but misinformation spread online about Rudakubana, who was born in Cardiff, led to a riot breaking out.
Posts claiming he was an asylum seeker who had arrived in the UK on a small boat were shared widely.
The violent unrest quickly spread around the country.
About 1,200 people have been arrested in connection with the riots in towns and cities across the UK, and more than 400 charged.
Dozens of them have been jailed.
