Police are believed to have identified the suspected perpetrators of the Novichok attack on Russian former spy Sergei Skripal and his daughter Yulia Skripal.
Officers think several Russians were involved in the attempted murder of the former double agent and daughter Yulia in Salisbury and are looking for more than one suspect.
A source with knowledge of the investigation told the Press Association:
“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. They [the investigators] are sure they [the suspects] are Russian.”
The news comes as an inquest is due to open on Thursday for Dawn Sturgess, 44, who died earlier this month, eight days after apparently coming into contact with Novichok from the same batch used in the attempted murder of the Skripals in March. It is understood Ms Sturgess was exposed to at least 10 times the amount of nerve agent the Skripals came into contact with.
Her partner Charlie Rowley, 45, was left fighting for his life after also being contaminated by the chemical weapon. Investigators are working to the theory that the substance was in a discarded perfume bottle found by Sturgess and Rowley in a park or somewhere in Salisbury city centre and Ms Sturgess sprayed Novichok straight on to her skin, the source said.
Sturgess and Rowley
Last week counter-terrorism detectives revealed they had found a small bottle containing Novichok at Mr Rowley’s home in Muggleton Road, Amesbury. They are trying to establish where the container came from, and how it came to be in his house.
