A group of anti-vaccine activists stormed an NHS ward with bogus legal notices and supposed evidence of Covid being a "hoax".
Footage from the bizarre incident shows a group of men walking up to a desk at NHS Colchester Hospital with a stack of brown envelopes.
The lead activist then reels off what each letter contains.
Among the evidence are documents about the "Nuremberg Code" - a set of research ethics outlining rules on human experimentation following the second world war.
Other envelopes contain evidence about international child protection laws, the UK Medical Alliance, and "Moto Caprio".
The female NHS worker initially refuses to take the documents, before the anti-vaxxer tells her it's a legal requirement to do so.


He starts a strange rant telling staff they are personally liable for Covid and "can't hide behind the NHS" because of the pope.
He said: 'You guys all have liability, you believe you can hide behind the NHS. [That] you can't be held in your personal capacity.
"Well the pope is head of businesses in the UK and across the world, and he stripped your liability in 2013, so the excuse of I'm accepting on behalf of the NHS, doesn't count."
He adds that the documents will be served through the post and that lawyers will follow up on them.
'I suggest you get your lawyers to have a look at that because it's all legally binding paperwork,' he added.
The conspiracy theorists then leave the office, but not before one can be heard say: "Yet another NHS business served."
One of the men, Michael Chaves, 55, is a former paramedic who has been known for peddling vaccine-related conspiracy theories online.
He runs the 'Mad Mix Conspiracies' Youtube Channel, where he tells thousands of viewers about the pandemic being a hoax, the MailOnline reports.
Among the videos are examples of other social figures being "served", including BBC Two presenter Jeremy Vine.
The video shows Chaves and his anti-vaxx pals pouncing on the newsreader in the street to serve him a "writ".
