The police officers pursuing two teenagers riding an electric bike minutes before they were killed in a crash were the first to arrive at the scene of the collision, a senior police chief has confirmed. Harvey Evans, 15, died alongside his best friend Kyrees Sullivan, 16, when the Sur-Ron bike they were riding crashed in the Ely area of Cardiff on Monday evening. Their deaths sparked rioting after video footage of a marked police van following the teenagers quickly circulated on social media.
