Rising British grime rapper Josh Ribera, 18, who performed under the name Depzman, was stabbed to death outside a nightclub in Birmingham on Friday, the Mirror UK reports. "He was so successful, I'd known him since he was about 12 and he was just a brilliant rapper," a friend of Ribera's told The Mirror. It shouldn't happen, this knife crime needs sorting now. He was at a fundraiser for his murdered friend, he shouldn't have died, it's just wrong man. An 18-year-old man has been arrested in connection with Ribera's murder after handing himself in to police. West Midlands Police say the motive for the attack is unclear.
