A video has been posted on Facebook showing a group of men planning, and then carrying out, an attack which leaves a cyclist crumpled in a road-side ditch.
The footage, which appears to be shot on a country lane somewhere in the UK, is filmed over the shoulder of the attacker. He is heard saying "get close to him and I'll knock him right in the hedge. Slow down to his speed," before the incident.
The cyclist is then filmed losing control and careering into road-side vegetation. It is unclear at this point if the victim was injured or not.
