New possible victim of nerve agent in Salisbury

A police officer was being tested yesterday at a hospital in England one week after a nerve agent sickened two people thought to have handled a contaminated item from the March attack on a Russian ex-spy and his daughter. The officer showed up at a hospital for medical advice and was transferred to Salisbury District Hospital for ‘‘appropriate specialist tests’’, the hospital said. The man and woman poisoned a week ago are in critical condition.
