Around a thousand people have gathered for a vigil at the spot where Kyrees Sullivan, 16, and Harvey Evans, 15, died in a road crash in Ely, Cardiff.
Many mourners are holding blue balloons and wearing white T-shirts adorned with pictures of the two boys, who died when their Sur-Ron electric bike crashed.
The mothers of the teenagers have asked that there be no people on Sur-Ron bikes at this evening’s vigil in Snowden Road.
The families have also requested the police are not present.
Dozens of blue and orange flares have been lit as the families of Harvey and Kyrees arrive on foot at the scene where hundreds of floral tributes and messages have been left since Monday.
Hundreds of blue balloons have also filled the sky in tribute to the teenagers and some fireworks have been set off.
A moment of silence was also held before the crowd broke out in applause.
It comes after the police watchdog is investigating whether actions taken by officers involved in a road crash which killed two teenage boys in Cardiff could be defined as a “pursuit”.
