Dash‑cam appeal issued after 5G mast arson in Oxford city, 2026

Key Points

• A 5G telecommunications mast has been deliberately set on fire in Oxford, the second such arson attack in the city within less than two months.
• The latest incident occurred between 11.10 pm and 11.35 pm on Wednesday, 29 April 2026, near the dual carriageway of the Eastern Bypass, close to the Rosehill and Littlemore roundabout and Sandy Lane West.
• The previous blaze took place around 8.45 pm on 5 March 2026 at a 5G mast near Cutteslowe Roundabout on the A40, causing a major A40 closure and temporary suspension of part of Oxford’s congestion‑charge system.
• Thames Valley Police have launched an arson investigation into both incidents and are appealing for dash‑cam and other CCTV footage, as well as any witness information.
• Firefighters attended both fires, cordoned off the areas, extinguished the blazes, and monitored temperatures for several hours before handing over to the responsible telecoms operators.
• A spokesperson for mobile‑network operator MBNL confirmed that the A40 mast was deliberately vandalised, with significant damage to telecommunications equipment, and that the company is working closely with police and the fire service.
• Local outlets, including the Oxford Mail, BBC News, ITV Meridian, and others, have reported on the incidents, highlighting disruption to traffic and concern over a pattern of 5G‑mast attacks.

Oxford(Oxford Daily)May 05, 2026 – Police are urgently appealing for dash‑cam and other video evidence after a second 5G telecommunications mast was set on fire in Oxford in less than two months, raising concerns about a spate of targeted attacks on mobile‑network infrastructure.

Detective Sergeant Lisa Jones, leading the investigation for Oxford CID, told ITV Meridian that officers are pursuing “a number of enquiries” to establish who was responsible for the arson at the Eastern Bypass mast and are particularly keen to obtain any dash‑cam or dash‑cam‑style footage from motorists travelling in the area between 11.10 pm and 11.35 pm on Wednesday, 29 April 2026.

Thames Valley Police have issued a non‑emergency contact number, urging people to call 101 and quote reference number 43260210718, or to report online or via Crimestoppers for 100% anonymity.

What exactly happened at the Eastern Bypass 5G mast in Oxford?

As reported by Adam Morgan of ITV News Meridian, the latest arson attack occurred at a 5G mast situated close to the dual carriageway of the Eastern Bypass, near the Rosehill and Littlemore roundabout and Sandy Lane West.

Morgan’s report states that the mast was set on fire deliberately and that emergency services were called to the scene, where firefighters from multiple stations worked to extinguish the blaze and secure the site.

Thames Valley Police later confirmed that the fire was taken seriously as a criminal act, with investigators treating it as a suspected arson rather than an accidental fault, and they have since disclosed that this is the second such 5G‑mast fire in Oxford in quick succession.

How did the earlier 5G mast fire on the A40 disrupt Oxford in March 2026?

Earlier, on 5 March 2026, a 5G mast located near Cutteslowe Roundabout on the A40 was also set alight in what officers described as a suspected arson.

According to a BBC News report, an unknown substance was used to ignite the mast around 8.45 pm, prompting the Oxfordshire Fire and Rescue Service to attend and speculate that the fire may have been deliberately started.

Drone footage published by ITV News Meridian showed the charred remains of the A40 mast, illustrating the scale of the damage. Fire‑service sources told ITV that firefighters cordoned off the area, extinguished the blaze, and monitored temperatures for several hours before handing the incident over to the telecoms operator and police.

The Oxford Mail and other outlets reported that the A40 closure caused more than 24 hours of disruption, with major traffic diversions and temporary suspension of part of Oxford’s congestion‑charge system while engineers worked to restore services.

What have the telecoms operator and authorities said about the damage?

In a statement quoted by ITV News Meridian, MBNL confirmed that the A40 mast attack “caused significant damage to telecommunications equipment” and that the damage appeared to be the result of deliberate vandalism.

MBNL added that the company was “working closely with the Police and Fire Service to ensure the area is safe” and that engineers were assessing the site to restore full connectivity.

A spokesperson for Oxfordshire Fire and Rescue told ITV that firefighters took the incident seriously both for public safety and infrastructure reasons, given the location beside a busy highway and the potential for fuel or electrical hazards.

How are police and media framing the pattern of attacks?

Citation:

“This is the second time in less than two months that a 5G mast has been set on fire in Oxford after a previous incident brought major disruption to the A40,” 

Thames Valley Police told ITV News Meridian.

BBC News, citing Thames Valley Police, similarly noted that the A40 incident was treated as a suspected arson and that investigations were underway into the circumstances surrounding the fire.

The Oxford Mail and other local outlets have highlighted that the repeated targeting of 5G infrastructure within a short period has raised alarm among transport planners and mobile‑network operators, who fear more widespread disruption to traffic‑management systems and mobile services if the pattern continues.

What is the background to this 5G‑mast arson development in Oxford?

Arson attacks on mobile‑network masts have occurred sporadically in the UK in recent years, often linked to conspiracy theory-driven misinformation about 5G technology, despite repeated reassurances from scientists and regulators that 5G is safe.

Oxford’s 2026 incidents come amid broader concerns about the resilience of critical digital infrastructure, especially where masts are tied into road‑safety systems, congestion‑charging schemes, and emergency‑communication networks.

Thames Valley Police and local authorities have previously warned that damaging telecommunications infrastructure is not only a costly criminal offence but can also reduce mobile‑phone coverage for emergency services, road‑safety cameras, and everyday users.

In this context, the March and April 2026 fires in Oxford are seen not just as isolated acts of vandalism but as part of a wider debate about public‑safety‑critical infrastructure and the need for stronger deterrence and community‑awareness campaigns.

What might this mean for residents, drivers, and telecom users in Oxford and similar UK cities?

If the spate of 5G‑mast arson continues or spreads to other locations, Oxford residents and frequent commuters could face repeated road closures, longer journey times, and temporary loss of mobile signal hotspots near key junctions such as the A40 and Eastern Bypass.

For telecom users, even partial damage to a mast can degrade voice, data, and emergency‑call performance in surrounding areas, particularly at busy times or during accidents where robust connectivity is most needed.

Looking ahead, local authorities and network operators may respond by increasing physical security at mast sites, installing more surveillance cameras, and stepping up public‑awareness efforts to counter misinformation about 5G, which could indirectly benefit both safety and the reliability of mobile services for drivers and smartphone users.

For the wider audience of UK motorists and mobile‑network users, the Oxford 2026 fires may prompt other police forces and infrastructure owners to review protection of roadside telecoms sites, potentially leading to tighter legislation against vandalism of critical communications infrastructure and more visible appeals for dash‑cam footage after similar incidents.
