Two more members of the Abergavenny and Brecon affinity group taking part in the London climate change protests have been arrested.

After Sadie Stanton was led away on Tuesday night, Rob Proctor and Sian Cox were both arrested by police on Thursday.

Around 570 arrests have been made since the beginning of the Extinction Rebellion protest which is still occupying Parliament Square, Marble Arch, Oxford Circus and Waterloo Bridge. Some protesters have centred their protest on Heathrow Airport

The demonstrators are demanding more urgent action from the government to tackle climate change.

On his release on Thursday Rob, from Abergavenny, paid tribute to the support he and his fellow protesters have been receiving from the public. He said: "The support from the public is phenomenal, even though we’re being disruptive, they are behind us."

Sian, from Brecon, was arrested and taken to Belgravia Police Station where she was held overnight before being released at 8.30am on Friday (April 19) pending investigation.After rejoining the protest in central London, Sian contacted the Brecon & Radnor Express at midday on Friday to say: "All protesters at my site (Oxford Circus) are currently surrounded (by police)."After Sian had been led away on Thursday afternoon, Janet Barker from Llangammarch Wells took her place in Oxford Circus protest. She said: "It’s incredible, over 500 have been arrested for peacefully protesting and yet even more are coming down to replace them. I am surrounded by people who are deeply committed and care so much for the future that we are prepared to do whatever it takes.

"I recently went to see my MP, Chris Davies, to ask him to do more on climate change but was then disapointed to find that he hadn’t even attended the Parliamentary debate on the subject.

"Now all we can do is resort to civil disobedience."

The Extinction Rebellion is calling on the UK government to reduce carbon emissions to zero by 2025 and establish a citizen’s assembly to devise an emergency plan of action.

Another protester, Angie Zelter, a pensioner from Knighton, spent seven hours in a cell at Brixton Police Station after she was carried off Waterloo Bridge by police on Tuesday afternoon because she refused to move when officers asked her to.

The 67-year-old immediately rejoined the protest after her release and on Thursday could be seen sat underneath a bright pink boat, donned with the words “tell the truth” which is moored in the middle of an Oxford Circus junction.A spokesperson for the Metropolitan police force said it was impossible for her to confirm all the names of the people who had been arrested because of the "sheer numbers" involved. She said the majority of people were arrested and released without charge after being taken away from the protest areas. A number will face charges at a later date.She put the figure for arrests since Monday morning at 570 - "as of 1000hrs on Friday 19 April" - and said that by Thursday evening 10 people had been charged, all for breaches under section 14 (5) and (9) of the Public Order Act.
