Police and firefighters have had fireworks thrown at them in "dangerous" Halloween night attacks.
Fireworks were thrown at police in Enfield, north London, with some 50 youths causing what officers described on Twitter as "carnage".
A 14-year-old boy was arrested after throwing fireworks at passing cars in the Edmonton Green area, police said on Twitter.
There were also injuries to "members of the public and children" as a result of "inappropriate dangerous behaviour", police said, adding that it had been a "frightening experience for officers on the ground".
One Twitter user said residents had been "terrified" and they were "surprised nobody suffered burns or other firework-related injuries".
In the Tinsley area of Sheffield, firefighters were called to a house fire, believed to have started after a firework was thrown through a bedroom window.
When they arrived, they were confronted by a group of youths and had fireworks and eggs thrown at them.
There were no injuries among the firefighters or the victims of the fire but South Yorkshire Fire and Rescue Service area manager Tony Carlin said the attacks were "appalling".
"Attacks like this place the safety of our firefighters, and the people they are trying to protect, at risk," he said.
"Thankfully, this type of incident is extremely rare in South Yorkshire and it is only a tiny minority of people who would ever consider acting in such an irresponsible and dangerous way.
"However, even one attack on a firefighter is completely unacceptable – and we will work alongside the police to fully investigate any attacks and ensure that those responsible are brought to justice."
In the Queensbury area of northwest London, fireworks were pelted at passing cars and pedestrians.
Police were called to the scene at 10pm but those responsible for throwing the fireworks had already left.
The Assaults on Emergency Services Workers (Offences) Act 2018 came into force this month, which includes tougher sentences for people who attack emergency services personnel.
