Reuters SALISBURY, England (Reuters) — British police have identified more than 200 witnesses and are looking at more than 240 pieces of evidence in their investigation into a nerve agent attack on a former Russian spy and his daughter, interior minister Amber Rudd said Saturday.
Former double agent Sergei Skripal, 66, and his daughter Yulia, 33, have been in hospital in a critical condition since March 4, when they were found unconscious on a bench in Salisbury.
The BBC reported late on Saturday that traces of the nerve agent had been found at Zizzi, an Italian restaurant where the Skripals had a meal before they were found unconscious. A police spokesman declined to comment on the report.
The restaurant, which has been closed to the public since the attack, was one of the sites being investigated by forensic teams.
There was also a flurry of activity at the cemetery in Salisbury where Skripal’s wife and son are buried, with forensic teams active in several parts of the site.
