In connection with the widespread riots that erupted in Cardiff following the deaths of two adolescents in an e-bike accident, nine persons have been detained.
After Kyrees Sullivan, 16, and Harvey Evans, 15, died in an Ely housing estate on Monday night, crowds threw objects at police and set fire to cars.
Social media claims that the police had been pursuing the pair just before the collision caused violence to break out.
South Wales Police initially said there had been no chase, but CCTV later emerged appearing to show a police van closely following two people on a bike minutes before the collision.
