A vigil for the victims of this week's deadly stabbing in Southport was disrupted by protestors, resulting in destruction and injuries.
Protesters, believed to be supporters of the far-right English Defence League, threw bricks at a local mosque, set vehicles on fire and threw bottles and bricks at police.
UK correspondent Gavin Grey says unconfirmed reports about the 17-year-old behind the attack may have prompted this attack.
