Anti-Semitic death threats have been sent to Chelsea boss Avram Grant in a package containing a mysterious powder, police have confirmed.
The football club´s training ground at Cobham, Surrey, was sealed off after a member of staff opened the package on Tuesday.
A note addressed to Grant, 52, claimed the powder was lethal and included the words: "You are a back-stabbing Jewish b******. When you open this letter you will die a very slow and painful death."
