Shooting suspect caught

Gunman sat down in church before opening fire, killing nine and letting one witness live

A 21-year-old white gunman accused of killing nine people at a historic African-American church in Charleston, South Carolina, was arrested on Thursday, said US officials, who are investigating the attack as a hate crime.

Law enforcement officials caught alleged gunman Dylann Roof, whose rampage on Wednesday came in a year that has seen months of racially charged protests across the United States over killings of blackmen.
