Two people have been arrested at Heathrow Airport on suspicion of committing terrorism offences.
A man and a woman were held at 8.30pm yesterday after arriving on a flight into the airport from Egypt.
The pair, both aged 26, were arrested by officers from the Metropolitan Police's Counter Terrorism Command on suspicion of the commission, preparation or instigation of acts of terrorism.
They were taken to a central London police station, where they remained in custody today. Police would not disclose the nationality of the suspects.
The arrests are part of an investigation into travel to Syria in support of alleged terrorist activity in the country.
Officers were searching two addresses in east London under the Terrorism Act in connection with their inquiries.
