Anti-Terror Arrests: Police Question Four Men
Police have arrested four men on suspicion of terror offences - three in London and one as he attempted to take a flight from Gatwick.
They form part of an investigation into travel to Syria in support of alleged terrorist activity.
Three men aged 18, 31 and 21, were arrested at separate addresses in east London in the early hours.
A 33-year-old man was arrested at Gatwick Airport on Wednesday as he attempted to take a flight out of the UK.
They are all being held in custody at a south London police station where they will be questioned by officers from the Metropolitan Police's counter terrorism command.
Sky's Crime Correspondent Martin Brunt said: "This is part of an investigation that has been going on for some months.
"For a while MI5 and Scotland Yard's counter terror unit have been concerned about several dozen, they think, British men, travelling to Syria and taking part in the civil war there."
