A man was attacked when he confronted youths setting off fireworks in Ellesmere Port on Bonfire Night.
The group of youths had congregated around Sutton Way at around 6pm.
When the man challenged them in Malpas Road, he was assaulted and received a head wound which required hospital treatment.
Police officers called out to the disturbance had fireworks and bricks thrown at them and their vehicles.
Public order patrols attended to disperse the youths and recorded those involved in the anti-social behaviour in order to identify those responsible.
Appeal for information
Now Cheshire Constabulary is appealing to anyone who saw the series of disturbances in the area or has information about the people involved.
Insp Mike Ankers said: “Last night, as well as deploying public order officers, we also got authorisation under section 60 of the Criminal and Justice and Public Order Act 1994 to stop anyone seen in the area to search for weapons, dangerous instruments or face coverings.
“This is a tactic that will continue to be used where necessary alongside stepping up patrols in the area and issuing dispersal notices.
“Clearly residents and businesses in the area affected last night do not want to see this type of criminal and intimidating behaviour in their community and we will take robust action against anyone committing anti-social behaviour.”
Anyone with information about the disorder should contact Cheshire police on 101, quoting incident number 719 of November 5, 2015.
Alternatively, information can be given anonymously by contacting Crimestoppers on 0800 555 111.
