"DEFRA [UK government's Department for Environment, Food and Rural Affairs] has today announced that the final site of decontamination in Salisbury is safe and has been handed to the South Wiltshire Recovery Coordinating Group," the statement read.
Deputy Chief Constable Paul Mills said that Wiltshire Police had cooperated with up to 26 partner organizations on decontamination operations.
"The policing operation locally has been unprecedented in its size. Over 15,000 individual police duties have been worked, across 20 cordons across the two areas alone. We have seen over 1, 200 police officers from 40 different police forces provide support to the local policing response and assistance to recovery," Mills said, as quoted in the statement.
He also pledged that investigation into the poisoning of Skripal and his daughter — as well as of UK police officer Nick Bailey, and late Dawn Sturgess and her boyfriend Charlie Rowley, who are believed to have been poisoned with the same nerve agent — would continue.
