Threatening letters calling for a "Punish a Muslim Day" on 3 April are being investigated by counter-terror police.

Muslims in London, Yorkshire and the Midlands have reported receiving the letter that calls for attacks in a points-scoring system.


The note incites verbal abuse and assaults on Muslims, as well as attacks on mosques.

West Yorkshire Police confirmed it had received six reports related to the letters.

The force said it had a couple of letters that will undergo analysis in an attempt to determine their origin.
