TEHRAN (Press Shia Agency) – Counterterrorism police in the UK are investigating a possible hate crime after families in East London received letters calling on them to attack Muslims on April 3, termed in the leaflet as "punish a Muslim" day.
Several Britons in London, the West Midlands and Yorkshire said they received the printed letter through the post, according to reports, Al Jazeera news network reported.
The leaflet says, "They have hurt you, they have made your loved ones suffer. They have caused you pain and heartache. What are you going to about it?"
It goes on to offer rewards for attackers, from 10 points for verbally abusing a Muslim and 50 points for throwing acid in the face of a Muslim, and to 1,000 points for bombing a mosque.
There are more than 2.5 million Muslims in Britain, where Islam is the second-largest religion.
On Saturday, West Yorkshire police joined London's Metropolitan Police in attempting to "catch the person or persons responsible for this".
"Public safety remains our priority and I would urge our communities to be vigilant but not frightened," West Yorkshire police said in a statement. "We are stronger when we stand together as one and will not be divided."
Tell MAMA, an organization monitoring anti-Muslim hate crime, said it was working with police.
"(The matter) is being treated with the utmost seriousness," the organization said.
"It is essential that all letters and envelopes are kept and handled minimally to preserve evidence for the police to investigate," the monitor said, advising recipients.
British Muslims, faith leaders, politicians and civil rights groups have expressed concerns and outrage at the development.
"This vile letter campaign sent to Muslims across the UK has caused deep distress and alarm. We welcome the action being taken by the police to investigate this matter," Miqdaad Versi, assistant secretary-general of the Muslim Council of Britain, one of the UK's largest Muslim umbrella organizations, said.
"Sadly, it is reflective of hate against Muslims which continues to manifest itself alongside the rise of the far right. Our elected officials need to stand up and take action against Islamophobia in the same way they have taken action to counter bigotry against other groups," Versi added.
Yasmin Qureshi, Labour Party politician and a practicing barrister, said, "I'm shocked to learn that extremist cowards are distributing anonymous letters encouraging people to attack Muslims."
Jess Phillips, Labour Party MP for Birmingham Yardley, said, "This is utterly unbelievable, if any of my constituents have received them please get in touch."
"Understandably, this is very distressful, not only those who have received the letter, but also for the wider communities," said Naz Shah, MP for Bradford West in West Yorkshire.
The head of counterterror policing in the northeast of England, Russ Foster, "has provided reassurance that a thorough and professional investigation is well underway and urges any further victims receiving any such communication to report the matter to the police", Shah said.
The Church of England's head of interfaith relations, Andrew Smith, tweeted, "Angry to hear about appalling 'punish a Muslim' letters that have been sent. Can't imagine how horrible & frightening it must be to get a letter like that. Time to redouble our efforts to build peace in our society & support those feeling scared or intimidated. The work goes on."
