A two-year-old girl was injured when she was hit in the face by a firework thrown into the garden of her home.
Police said the incident occurred at a house in Rockfield Heights in Newry, Northern Ireland, on Saturday evening.
She suffered a large burn after the firework was thrown while she was on her back doorstep with her parents.
The firework then exploded and set the curtains on the patio doors of the house on fire.
Police have launched a hunt for those responsible, BelfastLive reports.
A spokesman said: “Police are appealing for witnesses after a two year old child was injured by a firework thrown into the garden of her home in Rockfield Heights, Newry yesterday evening, Saturday 31 October.
“The little girl was standing on the back doorstep with her parents at around 8.15pm when the firework was thrown over the fence and struck her on her face causing a large burn. The firework then exploded and set alight the curtains on the patio doors, which were open. The child’s coat was also burned.
“Police are asking for help in identifying those responsible. Please call police in Ardmore on 101, quoting reference 2463 31/10/20.”
Elsewhere, fireworks were used against police in a “large-scale disturbance” involving a crowd of about 100 people, Police Scotland has said.
The force said people were setting off fireworks at officers and trying to intimidate them.
Extra police were needed to help break up the gathering, in Beauly Square, Dundee, with specially trained officers attending.
Inquiries into the incident, which took place at about 7.05pm on Saturday, are continuing, the force said.
Chief Inspector David Mcintosh, the local area commander for Dundee, said: “Luckily no one was injured during this disorder, however this kind of behaviour is completely unacceptable.
“Our main priority at the time was ensuring the safety of the public and our officers, however inquiries are ongoing to identify those involved in this disturbance and take the appropriate action.”
He said officers were currently carrying out additional patrols in the area to “provide public reassurance” and urged anyone with information about the disturbance to call the police.
