DETECTIVES are investigating online footage which appears to show a car being driven into climate protestors in Essex.

The incident took place near Junction 31 of the M25 in Thurrock last week when members of Insulate Britain blocked roads as part of a demonstration.

Essex Police said it has “identified those believed to be involved” after a video was released showing a woman drive into two activists blocking a road.

The footage shows an angry woman shouting “my son needs to get to school and I need to get to work so get out of the way”, before she gets back into her car and repeatedly drives it into the protesters.

Essex Police said its “inquiries are ongoing”.

It comes amid calls from Insulate Britain for road bosses to lower motorway speed limits to just 10mph when protests are taking place.

Dr Diana Warner, a member of Extinction Rebellion offshoot, demanded that National Highways work with protesters to “ensure safety for everyone” amid its efforts to block traffic on major roads.

Her comments came during a High Court hearing on Tuesday where a judge extended an injunction granted to Transport for London (TfL) against Insulate Britain.

In the hearing at the Royal Courts of Justice in London, Mr Justice Lavender extended the TfL injunction and granted permission for the list of named individuals it covers to be amended.

The judge said the injunction was extended either until a trial is held in the case or a further court order or April 8 next year.

“This doesn’t rule out the possibility that it could be extended again by a judge on a further occasion,” he added.

Last week, the court heard that National Highways may ask for a default or summary judgment – legal steps which would mean the case against the protesters is resolved without a trial.

Mr Justice Lavender also granted a request by TfL’s barrister, Andrew Fraser-Urquhart QC, for further disclosure of information by the Metropolitan Police relating to arrests.

During Tuesday’s hearing, Insulate Britain members were given the chance to address the court.

Dr Warner, a retired GP, told the court that Insulate Britain is “intent on keeping the public safe” and “committed to non-violence”.

The 62-year-old added that there is a “wide gulf” between her understanding of “what constitutes safety” and National Highways’ stance.

Dr Warner said National Highways should “slow the traffic to 20 miles per hour or 10 miles per hour when there are people are on the motorway”, warning that she expects to continue Insulate Britain’s campaign for “civil resistance” until “a meaningful statement from the Government that we can trust”.
