Four alleged members of a banned neo-Nazi group have been arrested on suspicion of terror offences.
The men, from the Midlands, Suffolk and Wales, were detained by counter-terror police in a series of raids and their homes are being searched.
West Midlands Police said the suspects are a 22-year-old man from Birmingham, a 32-year-old man from Powys, a 24-year-old man from Ipswich and a 24-year-old man from Northampton.
A spokesperson added: “They have been arrested on suspicion of being concerned in the commission, preparation and instigation of acts of terrorism under Section 41 of the Terrorism Act 2000; namely on suspicion of being a member of a proscribed organisation, National Action.
“All four men are being held at a police station in the West Midlands.”
They were arrested in a joint operation by specialist counter-terror units for the East Midlands, West Midlands and Wales.
“The arrests were pre-planned and intelligence-led – there was no threat to the public’s safety,” a spokesperson added.
Section 41 gives police the power to arrest anyone “reasonably suspected to be a terrorist” without warrant.
West Midlands Police would not give further details of the men’s activities but the “commission, preparation and instigation” of terrorism encompasses a wide spectrum of acts include directly planning an attack, joining a prohibited group or giving effect to that intention.
