LONDON—British counter-terrorism police said on Saturday they had recovered more than 400 items as part of their investigation into the murder of a woman in southwest England who was poisoned by the Novichok nerve agent.
Dawn Sturgess, 44, died on July 8, just over a week after being exposed to Novichok near the city of Salisbury where Russian double agent Sergei Skripal and his daughter Yulia were struck down with the same poison in March. The Skripals subsequently recovered.
