Assistant Commissioner Neil Basu, who is the national lead for counterterrorism policing, confirmed that Novichok, the nerve agent used to poison Rowley and Sturgess in Amesbury, is the same type of lethal toxin that was used just a few miles away in Salisbury, in a March attack on former Russian spy and British double agent Sergei Skripal and his daughter Yulia Skripal.
At this stage, Basu said, more forensic evidence is necessary to link the two incidents, but he added, "This is a very rare substance banned by the international community and for there to be two separate, distinct incidents in one small English county is implausible to say the least."
Police suspect that Rowley and Sturgess were poisoned after handling a container with Novichok. About a 100 counterterrorism detectives are working around the clock to locate it, according to Basu. He said scientists "will work hard to establish if the nerve agents from the two incidents are from the same batch." So far, police said there is no evidence that Rowley or Sturgess visited any of the sites that underwent decontamination following the attack on the Skripals in March.
