Spy probe gathers pace

POLICE investigating the suspected nerve agent attack on a Russian ex-spy and his daughter have identified more than 240 witnesses and 200 pieces of evidence.

Investigators are said to have found traces of a chemical weapon at the Zizzi restaurant in the southern English city of Salisbury.

Former spy Sergei Skripal, 66, and daughter Yulia, 33, reportedly ate at Zizzi in the hours before they were taken ill. Detective Sergeant Nick Bailey, who fell ill after tending to the pair, is recovering.
