Salisbury was the location of the poisoning of Sergei Skripal and his daughter with a nerve agent in March.
It is believed that at least one person has “fallen ill” in Salisbury in England.
According to the Salisbury Journal, witnesses described seeing police “covering someone up” with a blanket.
People inside the Old Ale Houe pub have been told that they are not allowed to leave, and safety crews donning hazmat suits are outside the restaurant.
Salisbury is where the poisoning of Sergei Skripal and his daughter took place earlier this year.
A fire engine, four police cars, an ambulance and an incident response unit were called to the scene.
Police were called by the ambulances at 6.45pm.
The pub, as well as the surrounding roads have since been cordoned off “as a precautionary measure”, while officers are investigating the scene.
There are no proven links to the poisoning that took place in the same area in March, but one witness described seeing “a man in a full white body suit with a mouth mask” at the scene.
