Metropolitan Police on Wednesday said the arrests were carried out in a joint operation by the Met's Counter Terrorism Command (SO15) and the Eastern Counter Terrorism and Intelligence Unit (ECTIU) in Luton town, 50 km northwest of London, Xinhua reported.
Those arrested were all in their 30s and were detained on suspicion of being involved in the commission, preparation and instigation of acts of terrorism. They have been kept in custody at a London police station, police said.
Seven separate addresses in Luton in connection with this investigation were searched, as well as a number of vehicles.
