SALISBURY, United Kingdom (AFP) – British police scrambled on Thursday to determine how a couple were exposed to the same nerve agent used on a former Russian spy earlier this year, as fear spread in the normally quiet English region where both cases took place.
The couple were taken ill on Saturday in the small town of Amesbury, close to the city of Salisbury, where former double agent Sergei Skripal and his daughter Yulia were found slumped on a bench on March 4 in an incident that sparked a diplomatic crisis with Russia.
“The possibility that these two investigations might be linked is clearly a line of enquiry for us,” said Neil Basu, head of Britain’s counter-terrorism police force.
British security minister Ben Wallace told BBC radio: “The working assumption would be that these are victims of either the consequences of the previous attack, or something else, but not that they were directly targeted”.
Police announced late Wednesday that tests on the couple, named locally as 44-year-old woman Dawn Sturgess and 45-year-old man Charlie Rowley, revealed they had been exposed to Novichok, but could not say whether it was the same batch used on the Skripals.
Novichok is a military-grade nerve agent developed by the Soviet Union during the Cold War.
Wallace repeated the British government’s accusations of Russian responsibility for the attack on the Skripals, which have been denied by Moscow, and said Russia could provide information that would protect local residents in Salisbury.
“We have said they can come and tell us what happened. I’m waiting for the phone call from the Russian state. The offer is there. They are the ones who could fill in all the clues to keep people safe,” he said.
Interior minister Sajid Javid is to chair an emergency cabinet meeting on Thursday, as counter-terrorism police lead the investigation into the incident.
Basu said there “remains a low risk to the general public,” saying “we’re satisfied that if anyone was exposed to that level of nerve agent by now they would be showing symptoms.”
However, many questions remain over the source of the contamination and why tests were not conducted on the couple until Monday, two days after they were taken ill.
“The priority for the investigation team now is to establish how these two people have come into contact with this nerve agent,” Basu said.
“We have no idea what may have contained the nerve agent at this time,” he said, urging members of the public not to touch anything if they did not know what it was.
Basu said there was no evidence to suggest that the couple “were targeted in any way”.
Local man Sam Hobson, 29, told AFP he was a friend of the pair and had spent time with them as they fell ill.
“I came around Charlie’s house in the morning and there were loads of ambulances outside, and his girlfriend was getting taken away,” he said.
“She was complaining of a headache in the morning and she went into the bathroom to have a bath and he heard a thump and she was in there having a fit, foam coming out of her mouth.”
She was hospitalised at around 0915 GMT. Hobson then went with Rowley to a church fair where Rowley complained of feeling unwell.
“He was sweating loads, dribbling, and you couldn’t speak to him,” Hobson said. “There was no response from him, he didn’t even know I was there. It’s like he was in another world, hallucinating.”
Hobson said he called the ambulance at around 1430 GMT.
Hobson also said that the couple had visited Salisbury on Friday, speculating that “they must have touched something that was contaminated.”
Basu said there was no evidence the man and the woman had “recently visited any of the sites that were decontaminated” after the poisoning of the Skripals.
Police had initially assumed that the two had consumed contaminated drugs.
But samples from both patients were sent to Porton Down defence laboratory on Monday “due to concern over the symptoms,” Basu said.
Both are still in a critical condition and are at Salisbury District Hospital — the same facility where the Skripals were treated. Police launched two helplines for those worried about possible contamination.
Police called for calm but also said that anyone who had visited any of the five sites that the man and the woman went to on Friday and Saturday should wash clothing worn at the time and wipe down personal items.
The sites, which have now been cordoned off, are a park and a homeless hostel in Salisbury, as well as a pharmacy, church and the house in Amesbury.
Skripal, 67, and his 33-year-old daughter Yulia, who was visiting from Moscow, were treated for weeks before being released from hospital.
The police said they suspected the nerve agent may have been smeared on a front door handle in liquid form.
The poisoning sparked a diplomatic crisis that saw Russia and the West expelling dozens of diplomats in tit-for-tat moves.
