Investigators wearing breathing apparatus and hazmat clothing searched two locations in Salisbury and Amesbury, on Friday. Policeman, paramedics and firefighters were stationed around the house of the couple thought to be poisoned by nerve agent Novichok. Dawn Sturgess and her partner Charlie Rowley lived on Muggleton Road in Amesbury. Another unit examined John Baker's house on Rollestone... Еще Street in Salisbury. It is thought Sturgess lived at this address for a period of time. The couple were taken to Salisbury hospital, after being found unconscious and in a critical condition at an address on Muggleton Road in Amesbury last Saturday. Police have since declared it a «major incident» and cordoned off a number of locations in the Amesbury and Salisbury area. UK counter-terrorism officers have also joined the investigation. Amesbury is a short distance from the UK chemical weapons laboratory Porton Down and the site where Sergei and Yulia Skripal collapsed after being allegedly poisoned by a nerve agent in March.
