Police seized a sound system from climate change protesters last night, just hours after hundreds of protesters lay on the floor of the Natural History Museum.

Officers cut the main power to the Extinction Rebellion camp in Marble Arch and then removed the sound equipment on Monday evening.

After a police cordon was put in place, officers could be seen taking away the various parts of a sound system, including a mixing desk and amplifiers.

It came not long after protesters took over the main hall of the Natural History Museum in their latest stunt of two weeks of demonstrations, on Monday afternoon.

Police have said they have a 'robust' plan in place ahead of a proposed climate change protest in Parliament Square on Tuesday.

The demonstration - which coincides with the first day Parliament is sitting following the Easter recess - is the latest action by Extinction Rebellion (XR) protesters in the capital.

Earlier on Monday more than 100 activists lay on the floor of the famous museum on a day which was supposed to be a 'pause' from their occupation of bridges and important locations in the capital.

It came as the leader of the Extinction Rebellion movement has said she is favour of escalating the protests this week.

Dr Gail Bradbrook said businesses and Government buildings could now be targeted by the climate change protests that have caused chaos to London and cost businesses more than £12m in the last seven days.

Police reopened Oxford Circus and Waterloo Bridge this morning, after the two sites were closed last week due to the arrival of the Extinction Rebellion group.

The protesters were planning to lie low at their base in Marble Arch today, as they move to open 'political negotiations' following last week's actions.

But they later appeared laying below the skeleton of a blue whale in the entrance hall to the museum in Kensington.

The museum was busy with families enjoying the final day of most schools' Easter holidays when the group moved in.

One father, who was at the museum with his two young children, said: 'I just think they are wasting police time. I think it's ridiculous. They are taking police away from where they should be.'

It came after police announced they have now made more than 1,000 arrests and charged 53 people over the disorder which brought parts of London to a standstill last week.

Speaking ahead of a 'People's Assembly' to decide on what will happen this week, Dr Bradbrook said she would support further mass protests.

But she told Mail Online she was not in favour of disrupting next week's London Marathon – one of the reported targets for the activists.

Dr Bradbrook said:' If the energy is still there, then I would be support an escalation of the protests. There will be discussions held from all those involved and a decision will be taken. But escalating what we have achieved is one way forward. We could target business or MPs.

'I don't think disrupting the London Marathon is such a good idea, but perhaps we could ask those taking part to acknowlege our movement and wear the Extinction Rebellion symbol.'

Her rallying call for an escalation in tactics will dismay Londoners who have faced a week of disruption as roads were closed and businesses lost trade.

Labour Shadow Cabinet member Barry Gardiner spoke to the group from their stage in Marble Arch this afternoon.

But his appearance angered some of the increasingly-fractious group's hardcore, who said he his party was 'helping the corporate take over of Britain through Brexit' that will, they said, 'reduce environmental regulations'.

Swedish activist Greta Thunberg, 16, also spoke to the crowd. She was met with cheers as she walked on stage and told a crowd of hundreds that humanity was at a crossroads.

One of the speakers at the assembly, Savannah Lovelock, 19, from Extinction Rebellion Youth, told a crowd of around 1,000 people at Marble Arch on Monday she was willing to quit university for the cause.

'I'm dropping out of university for this because there is nothing is more important than this,' she said.

Extinction Rebellion occupied bridges, jumped on trains and parked a boat in Oxford Circus, hitting businesses and commuters and leading to a hugely-expensive police operation.

Last night, the group moved back to Marble Arch, the only police-sanctioned protest space, where they are said to be discussing their next move.

With the protests set to enter their second week, the group's leaders are now at odds over whether to continue to protest or turn their attention to political negotiation.

Officials fear that if the protests do continue, they could disrupt the London Marathon, which is planned for next Sunday.

Farhana Yamin, from the group's political committee, said: 'Being able to 'pause' a rebellion shows that we are organised and a long-term political force to be reckoned with.'

But while admitting that no escalation was planned for Bank Holiday Monday, a spokesman for the group warned that the disruption would get 'much worse' if politicians were not open to their negotiation requests.

A Met Police spokesman said this morning: 'Overnight, Waterloo Bridge was re-opened and sites at Oxford Street and Parliament Square were also re-opened on Sunday 21 April.

'As such conditions are no longer required in these areas although officers remains at all three sites.

'We remain in frequent contact with the organisers to ensure that the serious disruption to Londoners is brought to a close as soon as possible and that only lawful and peaceful protests continue.'

Olympic gold medallist Etienne Stott was one of the activists arrested on Waterloo Bridge as police cleared the final section of carriageway on Sunday evening.

The London 2012 canoe slalom champion was carried from the bridge by four officers at around 8.30pm as he shouted of the 'ecological crisis'.

The group will no longer hold a picnic on the Westway by Edgware Road Underground station, which would have stopped traffic on the busy A-road on the last day of the long Easter weekend.

Instead, at Marble Arch, the only police-sanctioned protest space, activists will meet to 'vision what's going to happen in the coming week', an Extinction Rebellion member said, as she introduced Swedish activist Greta Thunberg to the stage.

The 16-year-old was met with cheers as she walked on stage and told a crowd of hundreds that humanity was at a crossroads.

Earlier on Sunday, in what the group later said was an internal memo intended to garner feedback from members.

Greta Thunberg, 16, vowed to fight back against world leaders who she accused of standing idly by while an 'ecological crisis' unfolds. The Swedish campaigner said: 'For way too long the politicians and people in power have got away with not doing anything at all to fight the climate crisis and ecological crisis. 'But we will make sure that they will not get away with it any longer.' Addressing climate activists at Marble Arch, she said: 'Humanity is now standing at a crossroads. We must now decide which path we want to take. 'How do we want the future living conditions for all living species to be like? Advertisement

The proposal suggests negotiating with the mayor of London, Sadiq Khan, and Metropolitan Police, to agree that they be allowed to continue their protests at one site in London.

Members would commit to not disrupting other areas in exchange for Mr Khan speeding up the implementation of the Declaration of Climate and Ecological Emergency, and considering setting up a London Citizens' Assembly.

They will also set up a political taskforce to take forward public negotiations with the Government, warning that they are prepared to scale up action depending on how much progress is made.

Neither the Met nor the Mayor's Office would say whether they were considering the proposals.

Boris Johnson, Mr Khan's predecessor as mayor, wrote in the Daily Telegraph that he was 'not in favour of paralysing public transport in the greatest city on earth' and said the UK was a 'world leader in reducing the greenhouse gases that are associated with climate change'.

He wrote: 'I am not saying for one second that the climate change activists are wrong in their concerns for the planet - and of course there is much more that can be done.

'But the UK is by no means the prime culprit, and may I respectfully suggest to the Extinction Rebellion crew that next Earth Day they look at China, where CO2 output has not been falling, but rising vertiginously.

'Surely this is the time for the protesters to take their pink boat to Tiananmen Square, and lecture them in the way they have been lecturing us.'
