An 18-year-old man has been injured after a firework exploded in his hand in Palmerstown, Dublin at about 9pm last night.
He was taken to Connolly Hospital by ambulance and Gardaí say enquires are ongoing.
This comes as 52 seizures of illegal fireworks have been made so far this year according to Minister for Justice Helen McEntee.
Ms McEntee launched a new campaign along with the Gardaí and the Dublin Fire Brigade highlighting the dangers of illegal fireworks earlier today.
The Garda operation which deals with the policing of Halloween has been brought forward as a result of the increase in fireworks.
The Minister says they do not know the reason behind the increase.
Fireworks have been a growing problem across Dublin in recent weeks, with residents in the county saying the noise from fireworks being set off has become constant at night.
Earlier this month, a task force to deal with the issue was set up following an emergency motion by Dublin City councillors.
The possession or use of fireworks, without an appropriate professional licence, is currently illegal in Ireland.
