UK counterterrorism police arrest 5 members of same family, including 3 teenage girls

British police say they have arrested five members of the same family, including three teenage girls, as part of a counterterrorism investigation.

Scotland Yard said the suspects were held on suspicion of "possessing information likely to be useful to a person committing or preparing an act of terrorism."

The five — a 51-year-old man, a 53-year-old woman, and girls aged 16, 17 and 19 — were arrested at an east London address Wednesday.

All five were in police custody at a London police station.

Police said the 16-year-old girl was first arrested last month on suspicion of preparation of terrorism.
