A police crime scene investigation van was set alight, and bricks were hurled at CSIs attending an incident in Leeds.
The CSIs were called to an address in Halton Moor on Thursday afternoon where a window had been smashed.
During the call out the CSI van was damaged, and police officers were called to attend, where they arrested a 31-year-old man on suspicion of criminal damage.
They were confronted by a group of youths throwing bricks, and one of the windows of an attending police car was also smashed.
The CSI van, which had been left in the street, was then damaged again and set on fire.
Additional officers and fire crews were called to the scene, where they extinguished the blaze as further bricks were thrown, though no injuries were reported.
A full investigation is ongoing, and a number of suspects have been identified. The man arrested remains in custody.
Chief Superintendent Steve Cotter, Leeds District Commander, said: “The behaviour of a minority of local youths during this incident was completely unacceptable, and I know the majority of the community are as shocked and disgusted as we are about what happened.
“We are carrying out a comprehensive investigation and will be taking appropriately robust action against those we identify as being involved.
“While we are still carrying out enquiries to establish the full circumstances, the background appears to be a pre-existing neighbour dispute that the police and our partner agencies have already been working to address.
“There is no suggestion that this incident was part of any wider feeling of hostility in this community. This behaviour, while completely unacceptable, did not constitute anything resembling a riot, and we think it’s important that people recognise how the use of such emotive terms is unhelpful to both the community and to ourselves in policing the area.
“Officers from the local neighbourhood policing team are maintaining a presence in the area today to reassure people and we will continue to work alongside our partner agencies in what remains generally a safe place with a strong community spirit.
“I would also encourage anyone in the community who has information that could assist the investigation to support our work and pass that on.”
