The man in Ilford is being held on suspicion of preparing terrorist acts and the 28-year-old has been arrested on suspicion of being concerned in the commission, preparation or instigation of acts of terrorism.

As arrests continue to mount, investigators released new details about the planning and methods of the three attackers and their van and knife rampage.

Pakistani-born British citizen Khuram Butt, from Barking, attempted to hire a 7.5 tonne lorry hours before the attack, although the group used a B&Q van loaded with bags of gravel instead.
