A man has today (22 October) been arrested in London on suspicion of attending a terrorist training camp in Syria.
Scotland Yard's counter-terrorism unit arrested the 32-year-old man and took him to a London police station, where he remains.
The man is suspected of "attending a place used for terrorist training", a Metropolitan Police Service statement said.
Address in west and south-west London are being searched as part of the investigation.
News of the man's arrest comes hours after the Met revealed a 25-year-old Bedfordshire woman had also been arrested for "Syria related" offences.
She was detained at a central London police station where she remains in custody.
Met commissioner Sir Bernard Hogan-Howe this week said at least five Britons a week are travelling to Syria to fight for the so-called Islamic State, or Isis.
