A 19-year-old man arrested at Heathrow airport on suspicion of "Syria related" terrorism offences has been released on bail, the Metropolitan Police have said.
Officers have since completed the search of an address in the Camden area of north London.
In a statement, the police said the arrest is "not in response to any immediate risk or threat".
A second man also arrested at the airport on Saturday on suspicion of assisting terrorism in Syria is still being held in custody.
