Police have arrested two men in connection with violent disorder in Batley last night.
The incident happened at around 20:40 on Staincliffe Hall Road, where witnesses described two groups of men fighting one another with baseball bats and other weapons.
Men were seen staggering down the street with bloodied faces.
A Mitsubishi Shogun deliberately rammed a Honda Civic before the disorder began, which is believed to have been a targeted attack.
A number of other cars were also damaged during the incident, with windows smashed through with weapons.
Four people went to hospital, all with what are thought to be minor injuries.
Police have arrested two men aged 27 and 29 from Dewsbury in connection with the incident.
Enquiries remain ongoing and a police scene is in place.
Detective Inspector Mark Atkinson of Kirklees CID, said: “An investigation is underway to establish the full circumstances of the incident.
“I am appealing to the public who may have seen either of these vehicles prior or after the incident and the occupants of the cars.
“We believed the incident between the cars, before the disorder broke out was a targeted attack.
“The incident caused considerable disruption last night in the local area, but thankfully no one was seriously injured.”
A West Yorkshire Police spokesperson said: "Anyone who witnessed the incident or has any information is asked to contact Kirklees CID via 101 quoting crime reference number 13180350413. Information can also be given to Crimestoppers anonymously on 0800 555 111."
