The highest concentration of the agent used against Sergei and Yulia Skripal was found on their front door. The pair were found collapsed on a bench in Salisbury on 4 March and remain in a critical condition. Police said inquiries would focus on their home address in Christie Miller Road but the risk to locals was low. Traces of the nerve agent had been found at some of the other sites in the city, but they were at lower concentrations.
