LONDON (AP) — Police and forensics officers scoured several sites in and around an English cathedral city Wednesday, as Britain’s security minister said authorities have new information about the mysterious substance that left a former Russian spy and his daughter in critical condition.
Home Secretary Amber Rudd said police would make a statement later in the day about what sickened Sergei Skripal, 66, and his 33-year-old daughter Yulia, who were found slumped on a bench in the center of the southern city of Salisbury on Sunday.
“We need to keep a cool head and make sure we collect all the evidence we can,” Rudd said. “And then we need to decide what action to take.”
Police kept residents away from an Italian restaurant and a pub in the city, and cordoned off part of a business park about nine miles (14 kilometers) away near the ancient stone monument of Stonehenge. Detectives appealed for information from anyone who visited either the Zizzi restaurant or the Bishop’s Mill pub in Salisbury on Sunday.
Bemused residents saw their usually placid town, famed for its 13th-century Gothic cathedral, turned into the center of a criminal probe with Cold War echoes.
With nerves still on edge, ambulances and emergency vehicles rushed to a building beside the Zizzi restaurant, which remains cordoned off. Witness Toni Walker said emergency services escorted two women from the building. Police and ambulance services declined to comment and it wasn’t immediately clear if the incident had anything to do with the ongoing investigation.
Rudd chaired a meeting of the government’s emergency committee, known as Cobra, to discuss the investigation, which is now in the hands of counterterrorism police.
“We do know more about the substance and the police will be making a further statement this afternoon in order to share some of that,” she said.
Her comments came as Moscow said the case was being used to fuel an “anti-Russian campaign” and further strain ties with Britain.
“What happened to Skripal has been immediately used to further incite an anti-Russian campaign in Western media,” Russian Foreign Ministry spokeswoman Maria Zakharova said.
Skripal, a former colonel in Russia’s GRU military intelligence service, was convicted in 2006 of spying for Britain and imprisoned. He was freed in 2010 as part of a widely publicized spy swap in which the U.S. agreed to hand over 10 members of a Russian sleeper cell found operating in America in return for four Russians convicted of spying for the West.
He and his daughter were found collapsed on a bench near a shopping mall Sunday in Salisbury, 90 miles (145 kilometers) southwest of London. Police believe they were exposed to a substance, and a British military research facility is thought to be conducting tests to determine what it is.
Foreign Secretary Boris Johnson told lawmakers Tuesday that if Moscow is shown to have been involved in the Skripal case, the government would act — possibly downgrading England’s participation in this year’s soccer World Cup in Russia.
While police say they are keeping an open mind about the case, it has reminded Britain of the 2006 poisoning of former spy Alexander Litvinenko.
A British inquiry into his death found that Russian agents poisoned him by lacing his tea with radioactive polonium-210 and that the killing was probably approved by President Vladimir Putin. Russia has denied any involvement in Litvinenko’s death, and this week said it wasn’t involved in Skripal’s collapse.
Litvinenko’s widow, Marina, wrote Wednesday in the Times of London that her husband’s case made clear to Britain’s emergency services that they need to act quickly when “someone suddenly falls mysteriously ill.”
“I am happy my story has raised awareness about the potential danger posed by Moscow, and this could help to save somebody’s life,” she wrote in an opinion piece.
British counterterrorism specialists have taken control of Skripal’s case from local police trying to unravel the mystery of what happened. The matter has not been declared a terrorist incident.
As speculation swirled, experts watching the matter say the circumstances so far suggest that it is unlikely that a radioactive substance was responsible, as was the case with Litvinenko.
Malcolm Sperrin, the former head of medical physics at the Royal Berkshire Hospital, said it would normally take time for a radioactive dose to become evident. Skripal and his daughter were seen on CCTV walking in the city only a short time before they became ill.
“If you were to give a dose of something radioactive, that could take many weeks” to become clear, he said — unless it were highly radioactive. In that case, those who came into contact with you would also be affected.
Most of the people who initially responded to the attack have been released from the hospital. Beyond that, there are too many unknowns to identify the chemical from arm’s length, he said.
“There are a lot of very exotic chemicals,” he said.
