Scientists rallied outside Charing Cross police station after an Extinction Rebellion activist and scientist started a thirst and hunger strike protesting the conditions under which she was being held.
Marine biologist Emma Smart, 44, was one of nine scientists arrested at the Business, Energy and Industrial Strategy (BEIS) on Wednesday.
She has been kept in a cell at Charing Cross police station waiting to be brought before a court on Saturday morning and has had nothing to eat or drink since Thursday morning, her husband, Andy Smith, said.
A spokesperson for the Met police said: ‘Decisions regarding bail are taken on a case-by-case basis and consider a range of matters including, but not limited to, whether there is a risk to the public or the person detained, the likelihood of someone not complying with any bail conditions or absconding and any previous history of offending while on bail. Whilst people are in custody, officers have a duty of care for their welfare and will ensure the medical needs of all detainees are considered. Health care professionals are available to each custody suite.’
