[Updated at 5:55 a.m. ET] Six people have been arrested in connection with the shooting of Malala Yousufzai, the teenage activist who spoke out against the Taliban, though the main suspect still is on the loose, Pakistani police told CNN exclusively.
Police on Wednesday identified Atta Ullah Khan, a 23-year-old from the Swat district where Malala was attacked, as the main suspect. Authorities are searching for Khan, who was studying for a master's degree in chemistry, police say. The Taliban-heavy Swat Valley is in the northwestern part of Pakistan.
