3 Arrests Made in Connection to Manchester Concert Bombing

Authorities in the U.K. have announced the arrest of three more people in connection with Monday night's Manchester Arena bombing that left 22 dead and dozens more injured. Only the bomber who blew up himself and scores of others have been named. That man, 22-year-old Salman Abedi, was a British-born national of Libyan descent. British Home Secretary Amber Rudd said Wednesday that it's "likely, possible, that he wasn't doing this on his own."
