A 12-year-old boy whose wheelchair was hit by a flare at a Sunderland match said he does not "feel safe" going back to the same stand.
Charlie was at the Stadium of Light when the missile was thrown into the disabled fans' section by Birmingham City supporters in the seats above.
"I was stuck in a big ball of blue smoke - I could have been in hospital," he told BBC Radio Newcastle.
Police are continuing to investigate what happened on Saturday.
Footage recorded by one fan shows what appears to be a flare land with a plume of blue smoke rising into the air.
