See what happened and where in Cardiff's night of riot chaos
On Monday two teenagers on a bike died in a crash in the Ely area of Cardiff, sparking a riot that resulted in cars being burnt and violent clashes with the police.
A police van was caught on CCTV just a few minutes earlier, following a bike about half a mile away from where the teenagers crashed.
South Wales police and crime commissioner said he was assured "youths were not being chased by the police".
