Teen 'planning to head to Syria'
An 18-year-old man has been arrested at his Birmingham home on suspicion of preparing to travel to Syria to join IS, police said.
The man, from Hodge Hill, was detained at about 07:00 GMT.
The operation was pre-planned and intelligence-led and there was no immediate threat to public safety, West Midlands Police said.
The man was arrested on suspicion of preparing for terrorist acts, contrary to Section 5 of the Terrorism Act 2006.
Meanwhile, three young British men who were stopped from travelling to Syria from Turkey and arrested have been released on bail, the Metropolitan Police says.
The three teenagers, two aged 17 and one 19, from north-west London, who were flown back to the UK on Saturday night, were arrested on suspicion of preparing terrorist acts.
