Broadband engineers have also faced physical and verbal threats from people who believe that radiation from 5G masts causes health risks and weakens people’s immune systems.
Liverpool Mayor Joe Anderson said he received threats after rejecting the theory as “bizarre”.
Cabinet Minister Michael Gove called conspiracy theories “dangerous nonsense.”
And NHS director Stephen Powis added, “The history of 5G is complete and complete. It’s nonsense – the worst kind of fake news.
“The reality is that cell phone networks are absolutely essential for all of us, especially in an age where we are asking people to stay home and not see their relatives and friends.
“But, in particular, it is also the telephone networks used by our emergency services and our health workers and I am absolutely outraged, absolutely disgusted that people are taking action against the very infrastructure that we need to respond to this health emergency.
“These are absolute and absolute garbage and I cannot condemn it in stronger terms than that. “
Culture Secretary Oliver Dowden is expected to speak to platforms such as Facebook, WhatsApp, YouTube and Twitter “to hammer home this message,” the source said.
Celebrities, including singer Anne-Marie, have helped spread the theory on social media. Amanda Holden, judge on England has an incredible talent, shared a link to an online petition claiming that the symptoms of Covid-19 were caused by living near a 5G mast. The petition has been deleted.
Emergency services were called to respond to the fires on the masts of Sparkhill, Birmingham, and on Antrim Road, north of Belfast, last Thursday, and in Melling, Merseyside, last Friday.
Videos of the arson attacks have been posted on social media.
