A new campaign is being launched to warn of the dangers of fans using flares and smoke bombs after it was revealed children as young as eight have been used to smuggle devices into football grounds.
The campaign by the Premier League, Football League and the FA comes after a number of recent incidents - including a linesman being struck by a firework at Aston Villa in October.
Concerns have intensified after CCTV at one Premier League ground caught a young boy handing out fireworks to adults from his rucksack.
Fans will be reminded that fireworks are illegal at matches and carry the risk of possible jail sentences, they will also be warned of the dangers involved.
Last season a 15-year-old boy suffered lung damage from a smoke bomb thrown at Wigan, while in February a 14-year-old boy was killed by a flare thrown by fans during a South American Libertadores Cup match in Bolivia.
The Premier League said in a statement: "A disturbing element of increased pyrotechnics has been the involvement of children.
"It is not uncommon for 'mules' to bring the pyrotechnics into a ground on behalf of others, and in one incident at a Premier League match last season a child aged around eight was observed aiding those involved in pyrotechnic use.
"The child came into the ground with pyrotechnics in his rucksack and was then seen passing them to members of an adult group who let them off inside the ground."
Fireworks have become a growing problem in English football with eight incidents in the 2010/11 season, 72 in 2011/12 and so far this season 96 incidents.
Nine people have been injured or burned by fireworks thrown at grounds in England in the last 18 months.
Last month a Manchester United fan who set off a smoke bomb during Sir Alex Ferguson's last game in charge, against West Brom, was given a suspended two-month jail term and banned from any football grounds for three years.
In February, two Chelsea fans were jailed for 28 days and given six-year football banning orders for taking smoke bombs into the Liberty Stadium for a match versus Swansea.
Policing minister Damian Green said: "Flares are very dangerous and can cause severe injuries. We are very lucky that no one has been seriously injured or killed by a flare here for a long time.
"This campaign clearly sets out the dangers of flares and smoke bombs. I want to see the courts taking this problem seriously and dealing in the strongest way possible with fans who still illegally smuggle pyrotechnics into football grounds."
