London: A former Russian double agent living in Britain following the biggest spy swap since the Cold War is in critical condition after suspected exposure to what police have called “an unknown substance”, British media reported Monday.
The BBC and other outlets named the victim as 66-year-old Sergei Skripal, who was hospitalised in intensive care Sunday along with an unidentified woman, in the English city of Salisbury.
Some news reports claimed the pair had been exposed to a deadly opioid in the incident.
A former colonel with Russian military intelligence, Skripal was sentenced to 13 years in jail in Russia in 2006 on charges of spying for Britain, but was granted refuge in the UK following a spy swap between the United States and Russia in 2010.
Police said Monday they had declared a “major incident” after two people - a man aged in his 60s, and a woman in her 30s - were found unconscious on a bench in a shopping centre in Salisbury, 85 miles (140 kms) southwest of London.
They remain in intensive care while a “multi-agency response” has been coordinated, Craig Holden, Temporary Assistant Chief Constable of Wiltshire police, said in a statement.
“Alongside our partner agencies, we are conducting some extensive enquiries to determine exactly what led to these two people falling unconscious and clarify whether or not any criminal activity has happened,” he added.
Holden said the force “received a call from a member of the public who was concerned for the welfare of two people” at around 4:15pm (1615 GMT) on Sunday.
“The pair, who we believe are known to each other, did not have any visible injuries and were taken to Salisbury District Hospital.
“They are currently being treated for suspected exposure to an unknown substance” he said, adding that they were “in a critical condition.”
A cordon around the scene of the duo’s discovery remained in place on Monday evening as police appealed for any witnesses to come forward.
A woman who saw them slumped on the bench told the BBC they “looked so out of it”.
The trust running Salisbury District Hospital advised people not to attend the emergency department “unless extremely urgent”.
Skripal was among 14 spies swapped by Moscow and Washington in 2014, in what was their biggest spy swap since the Cold War.
He was flown to Britain, where he had reportedly kept a low profile for the last eight years.
The retired Russian secret service colonel had been convicted and jailed for 13 years in 2006 for betraying Russian intelligence agents to Britain’s MI6 secret service.
His purported involvement in Sunday’s incident has echoes of Alexander Litvinenko, an ex-Russian spy who died in 2006 after being poisoned with radioactivity in London.
A British inquiry into the death said Russia’s President Vladimir Putin “probably approved” the killing and identified two Russians, Andrei Lugovoi and Dmitri Kovtun, as the prime suspects.
