Novichok attack: Police 'identify Russian suspects' in poisoning of Skripals
UK police are believed to have identified the suspects behind the Novichok nerve agent attack on a former Russian spy and his daughter.
Former double agent Sergei Skripal and his daughter Yulia fell ill after they were exposed to the substance in Salisbury in March.
Both have recovered and are being held in a secret location for their safety, with the UK government pointing the finger at the Kremlin for the attempted assassination.
A source told the Press Association police had identified the suspects behind the poisoning and confirmed they were Russian.
"Investigators believe they have identified the suspected perpetrators of the Novichok attack through CCTV and have cross-checked this with records of people who entered the country around that time," the source said.
"They are sure they are Russian."
The Metropolitan Police, who is leading the investigation, is yet to comment on the report.
The same batch of Novichok is believed to have killed another woman and left her partner critically ill in hospital.
Police believe Dawn Sturgess, 44, and Charlie Rowley, 45, handled the perfume bottle that held the substance used in the Skripal attack.
Ms Sturgess may have sprayed the nerve agent directly onto her skin and received a dose 10 times the amount the Skripals came into contact with.
She died in hospital on July 8, while Mr Rowley has since regained consciousness.
Police do not believe the couple were targeted directly.
More than 400 items have been collected by police in a case labelled by the UK's top counter-terror officer as one of the toughest in history.
"It is not an exaggeration to say that the search process linked with both this and the Salisbury investigation has been one of the most complex and difficult that UK policing has ever faced," Assistant Police Commissioner Neil Basu said on Friday.
"Not only are we trying to solve an extremely serious crime that has been committed, but we're also working to identify any potential outstanding risks to the public; all whilst ensuring that all those involved in the search process are not themselves exposed to any risk of contamination."
The attack on the Skripals led to the expulsion of Russian diplomats from the UK and US.
