British police on Wednesday said they had made a third arrest following the London Bridge terror attack which killed seven people and injured 48.
Rachid Redouane, 30, a self-described Moroccan-Libyan dual national was arrested in the eastern London suburb of Ilford, near Barking, where two of the assailants lived.
Police had previously identified attackers as Youssef Zaghba, a 22-year-old Italian national of Moroccan descent and Khuram Shazad Butt, 27, a Pakistan-born Briton. The two men were taken into custody while another 12 people held following the attack have since been released.
The Saturday attack was claimed by the militant Islamic State (IS) group and follows the May 22 suicide bombing at the Manchester Arena by Salman Abedi, killing 22 people.
The assailants drove a van into pedestrians on London Bridge, before descending into the nearby Borough Market where they stabbed people out for the night in the bars and restaurants.
