Police have arrested a 19-year-old man in connection with the London Bridge attack. 

Officers from the Met's Counter Terrorism Command, supported by the Territorial Support Group, arrested a 19-year-old man in Barking, east London at about 10pm last night. 

He was arrested on suspicion of being concerned in the commission, preparation or instigation of acts of terrorism under Section 41 of the Terrorism Act 2000.

A police spokesman said: "He has been taken into custody at a south London police station and is detained under the Terrorism Act.

"Searches of a residential address in Barking are ongoing."

Six other men remain in custody.

Eight people were killed when three men ploughed into pedestrians on London Bridge before stabbing people in bars and pubs in Borough Market.

The man arrested on Sunday is being held at a police station in south London.

Twelve others who were arrested in the early stages of the investigation have been released without charge.
