Four alleged members of the National Action neo-Nazi group have been arrested on suspicion on preparing acts of terror.
The group was listed as a proscribed organisation by the UK home office last December, after a number of organisations, including the Community Security Trust, urged the Home Secretary to ban it.
National Action members have previously threatened British Jews. Garron Helm, a National Action Merseyside member, was jailed last year for sending antisemitic messages to Luciana Berger, Britain's youngest Jewish MP, in February 2015.
