Gloucestershire Police have released footage of an altercation involving a cyclist and a woman on foot as they appeal for those involved and any witnesses to come forward.
The police footage shows a man, dressed in Wellington Boots and a flat-cap, cycling along a country road when he is approached by a woman on foot who pushes him.
She then appears to throw punches and kicks aimed at the man and his bicycle.
Police say the incident is believed to have happened at around 12.25pm on Saturday, January 28th on the B4425 at Ampney Coln near Bibury.
On the same day, a woman called Gloucestershire Police to report that she had been assaulted by a cyclist who had been holding up traffic.
In a longer version of what appears to be the same footage (not uploaded by police), the cyclist is seen "deliberately" cycling in the middle of the road for six minutes, according to text accompanying the video:
The longer video alleges that the cyclist is a hunt supporter aiming to stop hunt monitors reaching their destination.
After the altercation, passengers who recorded the footage then audibly thank the woman for clearing the road.
The woman, they say, appeared from another car behind.
Officers says they made a number of enquiries to locate this woman but it appears that the contact details she gave were incorrect.
As part of their enquiries officers seized footage that had been posted on YouTube that is believed to be connected to the same incident.
Investigating officers have been working to identify the individuals, but to no avail. They are now turning to the public for their help.
Police have appealed for the individuals captured on the film, or anyone who witnessed the incident, to contact Gloucestershire Police on 101, quoting incident number 187 of January 28.
