A 31-year-old was arrested on suspicion of assaulting a security guard the evening of Friday 29 January 2021 after Kent Police was called to a disturbance at around 2pm that day. He was taken into custody as enquiries continue.
The following morning, a further four men were arrested in connection with the incident and have been taken into custody.
As part of enquiries, detectives are appealing for anyone with information, including mobile phone footage and photographs of the disturbance, to contact them at the earliest opportunity.
A team of officers also remain at the barracks, as part of continuing enquiries.
No serious injuries were reported as a result of the incident, however a significant amount of damage was caused to one part of the site following a fire – which is believed to have been started deliberately.
Detective Chief Superintendent Andrew Pritchard, from Kent Police, said: ‘As part of our work, we are working in close partnership with the Home Office and Kent Fire and Rescue Service to help us establish the full circumstances and identify any individuals involved.
‘To help with our investigation I would encourage anyone with information, including video footage, to contact us as soon as possible.’
