The force has logged 589 reports in October so far, with youths accused of throwing fireworks at cars, properties and each other.
South Yorkshire Police said: “This is incredibly dangerous and frightening for victims. Please speak to your children ahead of Bonfire Night.”
Chief Superintendent Sarah Poolman, of South Yorkshire Police, added: “Fireworks are dangerous, they pose a risk to people’s safety and their property, as well as causing distress to many people living nearby.
“We know Halloween and Bonfire Night will be different this year for everyone, but anti-social use of fireworks is incredibly dangerous and frightening for victims and witnesses.
“We are taking a zero-tolerance approach to this and I urge parents to support us in relaying this message.”
Call 101 to report those involved.
