DUBAI: British police have launched an investigation after letters were posted to Muslims’ homes in the UK apparently calling for them to be killed and mosques to burnt down in a day of hate, UK daily The Mirror reported. The leaflets advertise a day in April called “Punish a Muslim” day, where people are encouraged to torture Muslims, carry out acid attacks and set fire to mosques. The hate-filled letters promised “rewards” to people who carry out the instructions, which range from verbal abuse, pulling off hijabs and even murder. “Pulling a Muslim women’s hijab is worth 25 points, an acid attack earns 50 points and burning or bombing a mosque will see the attacker collect 1,000 points,” the letter read. UK police forces have begun investigating the posts, which were scattered across the Midlands, West Yorkshire, and London. “The MPS does not tolerate any form of hate crime. If anyone believes they have been a victim of such an offense we would encourage them to report it to police so it can be fully investigated,” said a spokesman for the Metropolitan Police.
