Sergei Skripal and his daughter Yulia remain unconscious in a critical but stable condition following the attack on Sunday in the sleepy south-western English city of Salisbury. Sergeant Nick Bailey, one of first officers to find the pair slumped on a bench outside a shopping centre and who was later hospitalised in intensive care, was sitting up and talking on Thursday, according to police. "There's been around 21 people (treated)," said Kier Pritchard, chief constable for Wiltshire Police, noting that included "multiple officers." "A number of those have been through the hospital treatment process, they're having blood tests, they're having treatment in terms of support and advice," he added. Pritchard said he had spoken to Bailey and his wife in hospital, adding that "he's well, he's sat up" but was "very anxious." Authorities are racing to identify the nerve agent used against the 66-year-old Skripal, who came to Britain in a spy swap in 2010, as politicians warned it showed the hallmarks of an attack by Russia. Interior minister Amber Rudd told MPs that the "brazen and reckless" attack was "attempted murder in the most cruel and public way" but declined to single any perpetrator out. Noting it was "highly likely" that the officer, Bailey, was exposed to the same nerve agent as the Russian pair, she said Britain "will act without hesitation as the facts become clearer." The Russian embassy in London, which earlier in the week criticised Foreign Secretary Boris Johnson for blaming Moscow, welcomed Rudd's "responsible practical approach." Prime Minister Theresa May said that "if action needs to be taken then the government will do that," but urged "time and space" for the police to conduct their investigation. Russia suspected National counter-terrorism police have taken over the case, and on Wednesday confirmed that a nerve agent was used, adding they were treating the attack as attempted murder. "Scientific tests by government experts have identified the specific nerve agent used which will help identify the source," they said. Police have cordoned off the bench where the pair were found, as well as an Italian restaurant and a pub they visited before their collapse. They also sealed off the grave of Skripal's wife, Liudmila, who died in 2012 from cancer, as well as the memorial stone of his son, Alexander, who was cremated last year after reportedly dying of liver problems. As officers in biohazard suits worked inside secure tents, residents expressed shock at the attack in their midst. "You could be walking by and you could be involved in it, you know, it's quite shocking and worrying," Salisbury local Jackie Tothill told AFP. The Times reported that police are probing whether Skripal's daughter, who arrived in Britain from Moscow last week, may have inadvertently brought in the nerve agent as a gift. Ever greater threat Foreign Secretary Johnson has noted the "echoes" with the 2006 poisoning in London of former Russian spy and Kremlin critic Alexander Litvinenko, which Britain has blamed on Russia. Defense Secretary Gavin Williamson said Thursday that Russia was "becoming an ever-greater threat." Fellow Conservative MP Nick Boles tweeted that "I do not see how we can maintain diplomatic relations with a country that tries to murder people on British soil." Moscow accused British politicians and journalists of whipping up anti-Russian sentiment. Kremlin foreign ministry spokeswoman Maria Zakharova told reporters the story "was straight away used to boost an anti-Russian campaign in the media." The embassy added Thursday that when other Russians had died in Britain in suspicious circumstances, the authorities never released the findings, adding: "Same happening now." It cited Boris Berezovsky, a friend of Litvinenko found hanging in his bathroom in 2013, and Alexander Perepilichny, a businessman found dead in front of his home. No cause of death was determined in either case. Skripal was a former colonel in Russian military intelligence who was jailed in his country for betraying agents to Britain's MI6 secret service. He was pardoned before being flown to Britain as part of a high-profile spy swap involving Russia and the United States in 2010.
