A British neo-Nazi group has distributed among its members a list of police buildings and an image of a police chief, urging them to carry out attacks in retaliation for the arrest of one of its teenage followers.

The organisation, which calls itself the Feuerkrieg Division, shared the image of Dave Thompson, the Chief Constable of West Midlands Police, with a gun to his head and the words “Race Traitor” across his eyes.

The poster also reads: “Our comrade will be free… Responsible for the arrest of a 16-year-old National Socialist.”

According to the Times, Whitehall sources said they were aware of the group and its online presence.

The image was reportedly accompanied by a list of addresses of police buildings and sent to 500 members of a group on the Telegram encrypted messaging app.

A subsequent message said it contained all “publicly available police stations, training facilities, offices and detainment centres”, adding that they “should be considered high value targets to any local National Socialists”.

It also said: “These pigs should be advised that we know where they work… Heil Hitler and remember the names of these traitors.”

West Midlands Police said it is seeking those responsible.

Matthew Collins, of anti-racist charity Hope Not Hate, warned that a “new generation of Nazis” were targeting young gamers on online forums.

He said: “Do not think for a moment they are not seriously dangerous and deranged. They are encouraging children to do the almost unthinkable.”

It comes as Neil Basu, the Metropolitan Police assistant commissioner, said that far-right groups had begun to focus their attention online, copying the approach of jihadist groups.

Children aged just 14 are being groomed by political extremists, he warned.

The Feuerkrieg Division is thought to have been inspired by the Atomwaffen Division, a US-based neo-Nazi network.
