Q296: I have received a letter and there appears to be white powder in it, what should I do?
If you receive such a letter then put the letter down immediately do not open it. Call the police immediately who will advise you on the best course of action.
Many of the white powder letters turn out to be harmless things like cement and crushed sweets. However it is not worth taking any risks so do not open the letter and if possible clear the room where the letter is and do not allow anyone to touch it.
