Activists are demanding immediate intervention following an incident they have characterised as a vicious racially-motivated assault.
The confrontation occurred during a demonstration in the vicinity of Bicester town centre on Saturday, September 5, and was captured on film.
Footage appears to depict a male individual being forced to the ground and restrained with a stranglehold while subjected to what witnesses describe as racist insults.
The demonstration was staged by the Bicester Says No group, which objects to proposals for accommodating 1,256 single male asylum seekers at the MOD Bicester facility situated in Piddington.
The individual had navigated his vehicle through Claremont car park, which prompted jeering from those assembled, with audible remarks including get back to the third world.
He subsequently replied with what bystanders identified as a racist insult.
Ian McKendrick, deputy chairman of Oxfordshire Stand Up To Racism, offered his assessment that the incident plainly constituted a racist assault of a vicious nature.
He expressed concern that police characterisation of the matter as an altercation rather than an assault fell short of adequate response.
He noted that had the victim been white, he believed the language and measures employed would have been considerably more urgent.
He called upon authorities to apprehend the clearly identifiable individual responsible and ensure justice is served.
He emphasised that racist abuse and violent racially-motivated assaults have no place within the local community and must be eradicated entirely.
He stated that police bear responsibility for guaranteeing that no space exists for such violence within the county.
Thames Valley Police indicated awareness of the demonstration and confirmed that officers had been deployed to observe proceedings.
A force representative stated that during the demonstration, a confrontation transpired and officers promptly intervened to restore order.
An investigation has been initiated to determine the full circumstances, and at present no detentions have occurred.
A ratchet tool was recovered at the location and forms part of active inquiries.
The force recognised that the occurrence has generated considerable discourse and conjecture across digital platforms, and appealed to the public to refrain from speculation while inquiries proceed.
The representative further commented that the primary focus remains conducting a comprehensive and unbiased investigation while upholding the right to peaceful protest and maintaining safety for all communities.
Paula Ewers, who coordinated the demonstration, labelled the individual driving as aggressive but contested assertions that protesters had provoked him by striking his vehicle, dousing him with water, or expectorating upon him and his female companion.
She additionally denounced the use of racist language throughout the episode.
Ms Ewers observed that the only objectionable remarks originated from the individual recording footage, whose utilisation of racist terminology found no endorsement from anyone involved in organising the march or attending residents.
She indicated that the incident had instilled fear in numerous participants, preventing them from voicing their concerns.
She noted that the majority of those attending the demonstrations consist of individuals over fifty years of age, families with young children, and people with disabilities.
These constitute particularly vulnerable persons who now harbour concerns about facing aggression for expressing their anxieties.
