"I am appalled and shocked by the death of Dawn Sturgess, and my thoughts and condolences go to her family and loved ones. Police and security officials are working urgently to establish the facts of this incident, which is now being investigated as a murder. The Government is committed to providing full support to the local community as it deals with this tragedy," May said on Twitter.
On Sunday, the UK Metropolitan Police said that a woman, identified as Dawn Sturgess, died in a local hospital after being exposed to a toxic substance. The police have launched a murder inquiry.
Wiltshire Police Chief Constable Kier Pritchard said commenting on the incident that Dawn's death does not have an impact on the risk assessment for the population of Salisbury and Amesbury, which remains low.
On March 4, Skripal and his daughter were found unconscious on a bench at a shopping center in Salisbury. The United Kingdom and its allies have accused Moscow of having orchestrated the attack with what UK experts claim was the A234 nerve agent, albeit without presenting any proof. Russian authorities have firmly refuted the allegations as groundless.
