Mr. Clark said three of the four suspects in the investigation came from West Yorkshire, near Manchester. Based on forensic analysis obtained at the blast sites, he said police raided several homes. One person has been detained in what Mr. Clark described as a rapidly moving investigation.
More than 50 people were killed when the bombers struck the British capital's subway and bus system. Some 700 others were injured in the attacks.
