British police have arrested five people as part of an investigation following the deadly attacks in Paris and in Brussels.

West Midlands Assistant Chief Constable Marcus Beale says in a statement Friday that the arrests aim to address "any associated threat to the U.K. following the attacks in Europe."

Four people — three men aged 26, 40 and 59 and one woman, 29, were arrested Thursday in the central English city of Birmingham. A 26-year-old man was arrested at London's Gatwick Airport on Friday. The five were arrested for suspected ties to the commission, preparation or instigation of acts of terror.

Police are also searching a number of properties in Birmingham as part of the investigation.
