A vigil descended into chaos this weekend after fireworks were hurled towards police officers.
Shocking video, released by West Midlands Police, shows a masked figure taking aim on Longford Road in Coventry.
Fireworks can be seen exploding on the street as officers take cover from the sparks and thick smoke.
The incident took place during a ride-out in memory of motorcyclist Luke Cleary, 19, whose bike collided with a Ford Kuga.
Police have released footage of the firework incident and also shared images of three people they want to speak to.
Several officers were left with injuries.
A spokesperson for West Midlands Police said: ‘The clip shows fireworks repeatedly being hurled at a police van, putting police officers and members of the public in danger.
‘We’re urging anyone who recognises the three people from the clip or has any information to get in touch.’
Detectives arrested eight people on suspicion of affray and driving offences on Wednesday.
A 30-year-old man from Coventry was charged with driving without due care and attention, driving while disqualified and driving without a valid licence.
He was remanded to appear at Coventry Magistrates’ Court on Thursday.
Seven other between the ages of 15 and 48 were released on conditional bail, including a night-time curfew.
The force added that arrests are continuing and the investigation is ‘moving at speed’.
Detective Inspector Stew Lewis said: ‘If you recognise anyone from the video clip, we would urge you to get in touch. I would also appeal to those people in the clip, get in touch or expect a visit from us very soon.
‘We have released footage of fireworks being hurled at police vans and into the air not only to identify those responsible, but also to show the real risk to members of the public.
‘This could so easily have resulted in people being seriously injured.
‘Although our investigation is moving at a fast pace, we still need the public to get in touch with any information they might have.’
Anyone with information is asked to get in touch with West Midlands Police quoting log 1705 of August 21.
