On a quiet street in Ilfracombe, Devon, a woman in her 60s was filmed cutting wires atop a set of traffic lights on August 28, an act that has sparked debate and legal action. The woman, accompanied by a man in his 70s who steadied the ladder, was later arrested and released on bail on suspicion of criminal damage and endangering road users. The incident was shared widely on social media, attracting both condemnation and support.
The pair were identified as part of a group calling themselves the “Blade Runners,” who believe that traffic scanners installed above traffic lights are part of a secret surveillance system. These activists claim that the devices serve as “phased array electronic assault weapons” capable of monitoring the public and causing health issues such as cancer and dementia. Supporters have praised the woman’s actions online, urging for similar interventions in nearby towns like Bideford and Barnstaple.
Traffic scanners, commonly installed at intersections to monitor vehicle flow and pedestrian presence, have become targets for similar attacks beyond Ilfracombe. In May, nearly 200 traffic detector units were vandalized in Cambridge, prompting a police investigation. That same month in Sleaford, Lincolnshire, local councils reported damage to ten such sensors within one week, dismissing the conspiracy theories driving these acts as “ridiculous.” In Durham, a pensioner awaits trial on charges related to damaging traffic monitoring equipment across multiple locations.
Experts in transport technology find the hostility toward these devices puzzling. Susan Grant-Muller, professor of technologies and informatics at the University of Leeds Institute for Transport Studies, noted that such sensors have been in use since the late 1970s. She explained that the equipment does not record personal data such as faces or vehicle details but simply detects the presence of cars or pedestrians to help regulate traffic signals and ease congestion.
Advocates for pedestrian safety also support the use of these sensors. Tanya Braun, director of external affairs at the charity Living Streets, emphasized that improved monitoring at intersections can enhance pedestrian safety by optimising traffic flow.
Despite reassurances from experts, the conspiratorial views persist among some groups, who see the technology as part of a broader surveillance agenda. Clare Birchall, professor of contemporary culture at King’s College London, described this as part of a “super-conspiracy” related to fears surrounding what adherents call “the great reset.” Psychologists such as Stephan Lewandowsky, chair of cognitive psychology at the University of Bristol, note that conspiracy theories often emerge in response to unsettling events, providing adherents with a perceived way to assign blame and find psychological comfort.
