Police closed roads and called a hazardous response team Sunday night after two people became ill at a restaurant in the English city where a Russian ex-spy and his daughter were poisoned with a chemical nerve agent. Wiltshire Police described the emergency steps taken in response to "a medical incident" in Salisbury as a precaution. Authorities later lifted the alert and said no evidence of the nerve agent Novichok involved in the earlier case was found.(Photos: VCG)

Salisbury spent months with quarantine tents and investigators in full-body protective gear combing for evidence after Sergei Skripal and his adult daughter were found unconscious on a bench in March. Its residents were put back on edge in June when a man and a woman living in a nearby town were hospitalized with signs of exposure to the same Soviet-made Novichok. The woman, 44-year-old Dawn Sturgess, died.(Photos: VCG)

The restaurant is close to Queen Elizabeth Gardens where 44-year-old Dawn Sturgess was fatally poisoned by the nerve agent novichok at the end of June, the same chemical used to target former Russian spy Sergei Skripal and his daughter Yulia in March. (Photos: VCG)
