Nearly 100 protesters have been arrested at a demonstration in support of Palestine Action in central London.

Hundreds gathered in Trafalgar Square for the demo, which the WTXpolitan Police said was ‘likely to involve offending rather than a lawful protest’.

In a statement they said that as of 2.50pm, 92 people had been arrested on suspicion of supporting a proscribed organisation, but further arrests continue to take place. Those detained so far areaged between 27 and 82 years old.

Many of the mostly elderly demonstrators sat on camping chairs and on the ground as they held up their placards on Saturday.

At the top of the square, near the National Gallery, large banners were displayed reading ‘Jurors deserve to hear the whole truth’ and ‘Israel starves kids’.

Several protesters, including a man and a woman with grey hair, were carried off by officers away from the demonstration.

Police officers could be seen carrying a lady from the protest as people chanted ‘shame on you’.

Officers then lifted a man out in handcuffs and walked an elderly protester with a walking stick to the police vans.

One woman shouted: ‘Yeah she looks like a terrorist doesn’t she mate.’

Protesters accused police of dragging a woman out of the protest and not supporting her shoulders.

The woman could then be seen lying with her eyes closed as officers and bystanders surrounded her in a circle.

Others shouted at police that she needed medical attention.

One protester made the peace sign as she was removed while another said ‘Palestine Action is not a proscribed organisation’ as she was led off by police.

Protesters, some of whom were carried by their ankles and under their arms by officers, were led to an area at the side of Trafalgar Square surrounded by a metal fence.

One woman was seen smiling as she held up her hands in handcuffs while others sat on the ground in silence in the fenced off area.

Dozens of police officers were stood nearby as others moved in to remove protesters.

Protest group Defend Our Juries said the demonstration, called Everyone Day, would show the ‘resistance’ to the ban on Palestine Action is ‘stronger than ever’.

A female protestor holding a Palestine Action protest sign, said: ‘I’ve been arrested once before, but I wasn’t prepared to do it today for various reasons. I have grandchildren to look after. I’m here to support.’

The 69-year-old, who asked not to be named, was asked if being arrested put her off protesting and she said: ‘Of course not.’

She added: ‘It is the most important thing, and I’m old, in my lifetime, it’s huge. It’s a real takeover of the world and its resources. And it’s terrifying.

‘There is a massive genocide that has gone on for a really long time. They have a lust for murder, a lust for hanging. A lust for torture.’

Yael Kahn, who used to care for female political prisoners in Gaza before moving to England, said: ‘I wish, when my family was exterminated in the Holocaust by Nazi Germany, I wish there were people protesting, like all of these lovely people here. I absolutely adore them.’

Ms Kahn stood at the edge of the protest on Saturday with a ribbon that read ‘free Palestine hostages’.

She added: ‘The police are not arresting those people who actually, their hands, are full, covered in blood, of children, of women, of entire people in the Middle East or West Asia.

‘They are not questioning them.’

In March, the Met said officers would resume arresting suspected Palestine Action supporters, as a High Court battle over the ban on the group continues.

The police paused the arrest of demonstrators in February after the High Court ruled the Government’s ban was unlawful, but then decided to resume as an appeal against the ruling is likely to take several months.

Defend Our Juries said: ‘This issue affects everyone. From striking workers to peaceful protesters, everyone fighting for any worthy cause is at risk.

‘If left unopposed, what starts with an unlawful ban on one direct action group will lead on to the removal of everyone’s rights and freedoms.’

Speaking on the BBC Radio 4 Today programme on Saturday, former WTXpolitan Police chief superintendent Dal Babu said: ‘I think the difficulty is, when you’ve got 700 or 800 people who are willing to be arrested, that just isn’t practical. The optics of this will be very challenging for the police.

‘It will present some significant difficulties for the police in terms of how they manage it and also be aware of the fact there will be a huge amount of people who have sympathy with what is going on with the views of Palestine Action.’

He added that the decision to make arrests at the protest was an operational one, based on what intelligence the officers have.

He said: ‘I think they wanted to give clear guidance to the police officers that will be dealing with this matter. This will be an operational decision.

‘It will be based entirely on what intelligence they have, whether they have information around how many people are going to come out, what people intend to do, the kind of demonstration that they will do.’

Protesters have arranged mass rallies where demonstrators hold up signs saying ‘I oppose genocide. I support Palestine Action’, aiming to overwhelm the criminal justice system with the number of cases.

More than 3,000 people have been arrested so far for allegedly expressing support for Palestine Action since it was banned as a terrorist group last year, including more than 2,400 in London.

Seven people were arrested on suspicion of supporting the banned group, at an RAF base in Suffolk on Sunday, during protests against the Iran war.

In March, 18 Palestine Action supporters were arrested after staging a demonstration outside New Scotland Yard in support of the group.

The trials of hundreds of people accused of holding up the placards have been put on hold while the High Court case over the ban continues.

Proscription makes it a criminal offence to belong to or support Palestine Action, punishable by up to 14 years in prison.
