Two Russian spies charged with launching the Salisbury novichok attack arrived in the UK just two days before attempting to assassinate Sergei Skripal and fled back to Moscow hours later, police have revealed.

Investigators painstakingly combed through 11,000 hours of CCTV footage to compile a timeline of the movements of two men who were using genuine Russian passports in the names of Alexander Petrov and Ruslan Boshirov, which are believed to be aliases.

Theresa May said the men were members of Russia’s GRU military intelligence agency, after authorities issued European Arrest Warrants and Interpol red notices.

“Should either of these individuals ever again travel outside Russia, we will take every possible step to detain them, to extradite them and to bring them to face justice here in the United Kingdom,” the prime minister said.

After flying to London from Moscow on 2 March, they carried out a reconnaissance mission to Salisbury the following day, then returned on 4 March to deploy the nerve agent.

They were caught on CCTV near Mr Skripal’s house at noon, and by the time the former Russian double agent and his daughter fell ill the pair were on their way back to London to catch a flight back to Moscow.

Police are appealing for information to fill in any gaps in their knowledge, and trace how then men disposed of a novichok bottle they believe was later found by Charlie Rowley.

The 45-year-old cannot remember exactly where he picked up what appeared to be a Nina Ricci perfume in Salisbury, before giving it to his partner Dawn Sturgess as a present.

The mother-of-three died days after spreading the nerve agent it contained on her wrists, while Mr Rowley was left critically ill and has since been readmitted to hospital.

“The toxic chemical compound displays the same toxic properties of a nerve agent. It is also the same toxic chemical that was found in the biomedical and environmental samples relating to the poisoning of Mr Sergei Skripal, Ms Yulia Skripal, and Mr Nicholas Bailey on 4 March 2018 in Salisbury,” investigators say.

Crown Prosecution Service announces criminal charges against two Russian suspects, who Theresa May identifies as GRU spies.

Police launch appeal for information on the suspects, their movements and the “perfume” bottle.

“The manner in which the bottle and packaging has been adapted makes it a perfect cover for smuggling the weapon into the country, and a perfect delivery method for the attack against Mr Skripal’s front door,” Mr Basu said.

“The lack of crossover between the known movements of the suspects and Dawn and Charlie’s known movements around Salisbury, and the fact that there is no evidence to suggest they have been targeted mean it is much more likely Dawn and Charlie found the bottle.”
