HOUSTON (AP) — A white Houston-area man was arrested Thursday on federal hate crimes charges for allegedly shooting video of himself sucker-punching a 79-year-old black man in a “knockout game”-style attack. Conrad Alvin Barrett, 27, made a brief appearance before U.S. Magistrate Judge Frances Stacy, who scheduled a detention hearing for the Katy man on Friday. According to prosecutors, the attack happened Nov. 24 in Katy, but it wasn’t until 12 days later that authorities connected the attack to the cellphone video of it.
