UPDATE: Police confirmed this afternoon (Tuesday, September 11) that a 15-year-old girl has been arrested on suspicion of causing actual bodily harm following an incident in Whitby Park. She has been released under investigation pending further enquiries.

POLICE in Ellesmere Port have confirmed they are investigating a vile bullying video that surfaced on Facebook over the weekend.

The footage shows a gang of youths surrounding another teenage girl while another girl spits in her face, shouts at her and eventually attacks her.

All the while the main aggressor is goaded to punch the victim while others jeer and record the scene on their mobile phones.

Cheshire Police confirmed an incident took place at around 6.45pm on Saturday (September 8) at the entrance to Whitby Park in Ellesmere Port.

A spokesman said officers were called after the incident, which is being treated as an assault, and are now following up lines of enquiry.

Around 517,000 people have now viewed the video after it was shared by comedian, commentator and bully-shamer Robin Armstrong on his Facebook page.

He wrote: “This disgusting video happened in Ellesmere Port, Cheshire. A girl is standing surrounded by a screaming crowd of kids laughing and egging the girl on to be attacked while one of them spits in her face to try and get a reaction so she can start the assault!

“Makes my blood boil just listening to them, desperate for her to be hit! Her excuse? Childish Chinese whispers ‘she said you said’. Look at how terrified that poor girl is and with only one person trying to help! Shame on the lot of you!”

The footage, which can still be viewed on Mr Armstrong’s page, shows the teenagers calling the girl a “f***ing bitch’, shouting and jeering.

The principle aggressor – a shorter girl dressed in black with dark hair – can be seen smirking at the camera in between screaming at her victim.

The girl, wearing a pink jacket, tries to walk away several times but is blocked on each occasion. At one point she asks ‘can you go away?’ before the girl in black screams ‘no!’ inches from her face.

One lad tries to stand up for the girl, even putting himself between her and the aggressor, but is told to move out the way.

Someone in the crowd shouts ‘t**t her!’ before a scuffle takes place between the two girls to the delight of the bystanders.

In his video following the footage, Mr Armstrong said it was “like a crowd at an execution” with the youths “snarling and laughing”.

“That must have been one of the most terrifying moments of her life,” he said, paying tribute to the one boy who stood up for her.”

“Big well done to you – you’re the hero mate,” he added.
