Six people have been arrested on suspicion of belonging to far-right group National Action.

One woman from Banbury and five men from Cambridge, Banbury, Wolverhampton, Leicester and Stockport were detained .

Police said the suspects were aged between 21 and 37 and are being held on suspicion of being concerned in the commission, preparation and instigation of acts of terrorism under Section 41 of the Terrorism Act 2000.

The arrests were all pre-planned and intelligence led and there was no threat to the public's safety.

Five specialist counter-terrorism units were involved in the raids and investigators are continuing to search the suspects' homes.

The operation came as three other alleged National Action members were due to appear at Birmingham Crown Court in an unrelated terror case.
