TRACES of the nerve agent used to poison Sergei and Yulia Skripal have been found in a Salisbury restaurant. 

The trace was found during the ongoing forensic investigations at Zizzi in Castle Street, according to BBC sources. 

The former Russian spy and his daughter ate in the restaurant on Sunday, about two hours before they were found slumped on a bench in the Maltings. 

Currently there is no suggestion that anyone else who was in Zizzi at the same time is in danger. 

Officers closed off the restaurant on Monday evening, but put up a large screen blocking it from public view last night. 

The investigation continues at a number of locations throughout the city, including the bench the pair were found on, Bishop’s Mill pub in the Maltings, Mr Skripal’s home in Christie Miller Road and around the graves of his wife and son.
