Five men arrested a week ago under the Terrorism Act have been released by police into the custody of the Immigration Service.
Three residential addresses were searched
The men were arrested with five others. They are the last to be released without charge, Scotland Yard said.
They were all arrested in connection with suspected international terrorism in the UK.
The arrests involved police from the Met, West Midlands and Derbyshire, as well as anti-terrorist branch officers.
The men were held on suspicion of the commission, preparation or instigation of acts of terrorism.
Four of them - arrested in Wolverhampton - were released on 12 October, while one man arrested in Derby was also released last week.
Of the five released on Saturday, three were arrested in Croydon, London, and two in Derby.
Three residential properties were searched as part of the investigation.
