A driver fed up with Insulate Britain protests took matters into his own hands, dragging a protester off the road and tying him to a railing by his backpack, with his own banner.
The tension-fuelled incident was captured on video, with footage showing two grey-haired protesters on their backsides being pulled off the road by two men - presumably drivers frustrated at the blockage.
A chorus of horns and shouts can be heard as the man and woman are hauled off the road, while a truck and a stream of cars who had been held up, carry on their way.
While the man pulling the female protester lets her go once she’s safely off the road, the second driver continues to drag the male protester to a strip of metal railing on the other side of the pavement.
Once his backpack is up against the railing, he proceeds to thread the protester’s ‘Insulate Britain’ banner through the railing and around the straps of his backpack, securing it and subsequently him, to the metal fencing.
The protester turns his head to either side in an attempt to see what is going on behind him, but does not appear to be struggling to free himself.
While it was not clear where the video was shot, people commenting on the video online suggested the incident took place last week.
On Thursday the Insulate Britain group penned an open letter to Prime Minister Boris Johnson saying it would halt its “campaign of civil resistance” "ahead of COP26, until 25 October.
The campaigners blocked the M25 on at least 13 days in the past six weeks as they called for the government to introduce heat-saving measures in social housing.
The group, an offshoot of Extinction Rebellion, has since its first protest on September 13 been taking to the roads of the motorway encircling London to block cars as they protested against carbon emissions.
The group is calling for a national programme to ensure homes are insulated to be low energy by 2030.
It wants the government to fund the insulation of all social housing by 2025 and publish a "legally-binding national plan" for a low energy and low carbon retrofit of all homes in Britain by 2030.
Its campaigners' methods of blocking major roads and gluing themselves to tarmac has exercised many, including the Transport Secretary.
Last week Grant Shapps branded the protest group "pathetic", insisting their actions, which caused disruption to major roads during the last five weeks, are "absolutely unacceptable".
He told LBC: "What they're doing is pathetic, dangerous, irresponsible, counter-productive, and the fact that they then apologise to drivers for the delay, the stress they're causing, is absolutely unacceptable.
"I've seen a van driver who lost his job because he was an hour late, on TV. I saw an HGV driver who was trying to deliver fuel, during the fuel crisis the other week. A woman who was trying to visit her mum in hospital.
"Parents trying to get their kids to school."
On Sunday, the group posted an alarming video showing a clash between protesters and a mother on the school run last week.
The furious mum almost ran over an Insulate Britain environmental protester while her son sat in the car.
In the footage a man can be heard shouting "that's it, push them out of the road" as the woman approaches.
She drives her car right up behind two of the protesters, stopping the large vehicle as it touches the back of one of their heads.
With the SUV towering over the woman as she sits on the floor, the enraged driver gets out of the vehicle and strides through the group's signage.
"I'm not joking, my son needs to get to school," she says. "My son is 11 and he needs to get to school and I need to get to work."
The woman returns to her car and begins driving it into one of the protesters, who grimaces and cries out "ow, ow, ow".
A man shouts "well get out of the road then you silly c***" before the woman and her young son started screaming at her from the doors of the car.
It appears the video was shot when Insulate Britain targeted an industrial estate near the Dartford Crossing at Purfleet, Essex.
