Five people have been arrested on suspicion of being members of far-right terror group National Action.

Three men, a woman and a teenage boy were detained following a series of arrests across the country.

The individuals are being held at a police station in the West Midlands.

They are a 22-year-old man from Birmingham, a 23-year-old man from Halifax, a 22-year-old woman also from Halifax, a 28-year-old man from Birmingham and a 17-year-old boy from Nottingham.

All five "will be questioned on suspicion of being members of a proscribed organisation (National Action) contrary to section 11 of the Terrorism Act," West Midlands police said in a statement.

The arrests were carried out by West Midlands Counter Terrorism Unit in conjunction with CTP North East and East Midlands CTIU. They were pre-planned and intelligence-led.

A number of properties are also being searched in connection with the arrests.

Former home secretary Amber Rudd made National Action a banned group in December 2016.

In March 2017, an undercover investigation by ITV found that its members were still meeting in secret.

In the official list of proscribed groups, it is described as a "racist neo-Nazi group" that was established in 2013 and has branches across the UK.

It is the first extreme right-wing group to be outlawed in the UK.

The proscription means that being a member of or inviting support for the organisation is a criminal offence, carrying a sentence of up to 10 years in prison.

The group has held numerous marches and demonstrations on Armistice Day and Remembrance Sunday, and celebrated the election of Donald Trump as US president.

When she banned the group, Ms Rudd said: "National Action is a racist, anti-Semitic and homophobic organisation which stirs up hatred, glorifies violence and promotes a vile ideology, and I will not stand for it.

"It has absolutely no place in a Britain that works for everyone."

At the beginning of this year, police arrested five men and a woman on suspicion of being members of the banned group.
