With spiralling tensions between Sikhs and Muslims, Britain may be facing a threat more deadly than the anthrax-laced letters terrifying America, in the form of a single, poisonous, unsigned sheet of paper that has been doing the rounds of the northern English city of Derby for many weeks.

Muslim leaders say the letter is a hoax and designed to whip up communal tension.
