Mobile phone masts have been torched and engineers abused over “baseless” theories linking coronavirus to 5G.
UK mobile network providers have warned against the spread of the theories after videos showing masts on fire were posted on social media.
Masts were set alight in Sparkhill, Birmingham, on Thursday and Melling, Merseyside, on Friday.
Trade body Mobile UK, which represents network providers, said the false rumours and theories were “concerning”.
In a statement on Twitter, the Department for Digital, Culture, Media and Sport said it was “aware of inaccurate information being shared online about 5G”.
“There is absolutely no credible evidence of a link between 5G and coronavirus,” it added.
In Melling, Merseyside Fire and Rescue Service said it extinguished a 5G mast tower fire near the M57 motorway late on Friday.
There was damage to the mast and control panels, a spokesman said.
West Midlands Fire Service said the fire in Birmingham on Thursday involved a 70ft tower on a telecommunications site. However, the service said the cause was yet to be identified and could not confirm the mast was 5G.
A West Midlands Police spokesman said: “We’re aware of a fire involving a phone mast, but are awaiting further details on its cause.”
On Friday, Facebook removed a page which showed several videos claiming to show 5G towers on fire and encouraged others to do the same.
In addition to warning on the theories about the safety of 5G technologies, Mobile UK added: “More worryingly some people are also abusing our key workers and making threats to damage infrastructure under the pretence of claims about 5G.
“This is not acceptable and only impacts on our ability as an industry to maintain the resilience and operational capacity of the networks to support mass home working and critical connectivity to the emergency services, vulnerable consumers and hospitals.”
