LONDON - British police arrested two people at Heathrow airport on Saturday on suspicion of 'terrorism'-related activities in Syria, they said. A 19-year-old man was arrested on suspicion of 'preparing for acts of terrorism' in relation to Syria and a 20-year-old man was held on suspicion of 'sending property overseas for the purpose of assisting terrorism in Syria.' A police spokesman said the two arrests were not connected. Officers from the Counter Terrorism command unit made the arrest but police said the detention of the 19-year-old was not in response to any immediate risk or threat.
