On 29 July last year, three young girls were stabbed to death while attending a Taylor Swift dance class.
Bebe King, 6, Elsie Dot Stancombe, 7, and Alice da Silva Aguiar, 9, were killed by Axel Rudakubana, who was jailed for a minimum of 52 years.
A day after the attack, riots broke out on the streets of Southport and over the coming days spread right across the nation.
The protests were fuelled by false claims on social media that the perpetrator of the Southport attack was a Muslim and an asylum seeker.
