“On Wednesday ... a small bottle was recovered during searches of Charlie Rowley’s house in Amesbury,” police said in a statement. “Scientists have now confirmed to us that the substance contained within the bottle is Novichok.”
More tests were being carried out to try and establish whether it is from the same batch that contaminated the Skripals and inquiries were under way to establish where the bottle came from, the statement added.
“This is clearly a significant and positive development. However, we cannot guarantee that there isn’t any more of the substance left,” said Assistant Commissioner Neil Basu, Head of UK Counter Terrorism Policing.
He declined to give further details on the bottle, but police said inquiries were ongoing to establish where the bottle came from and how it came into Rowley’s possession.
Further tests are also being carried out to see if the Novichok came from the same batch that was applied to the front door of Skripal’s house in Salisbury.
Britain and its allies blamed Russia for the attack in March on the Skripals, prompting the biggest Western expulsion of Russian diplomats since the Cold War. Moscow has rejected the accusations and has hit back by expelling Western diplomats.
Britain has invited independent technical experts from the international chemical weapons watchdog to travel to the UK early next week to independently confirm the identity of the nerve agent, the British Foreign Office said on Friday.
An inquest into Sturgess’ death is set to open and adjourn in Salisbury on next Thursday.
