A gang assaulted three teenagers in separate attacks in Cleckheaton in the early hours of Saturday morning.
The first offence happened between 1.30am and 2.20am near The George public house in Market Street, Cleckheaton. Six men approached the 18-year-old victim and assaulted him, causing facial injuries.
A short time later, two 17-year-old males were assaulted at the junction of Market Street and Bradford Road. Both men sustained facial injuries and other injuries to the body.
The group of men have walked off along Bradford Road in the direction of Cleckheaton Town Hall.
The six men are all described as white and aged around 20-years-old.
One of the men, who assaulted one of the 17-year-old victims, is described as 5ft 9ins tall. of stocky build, with short, light ginger hair and darker ginger stubble. He was wearing a light blue bomber-style jacket, jeans and pumps.
PC Chris Birkenshaw, of Batley and Spen Neighbourhood Policing Team, said: “These appear to be completely unprovoked assaults with no apparent motive which have resulted in one victim requiring hospital treatment and two other victims also being injured.
“We are keen to speak to anyone who has witnessed any part of these offences or with information about the group involved.”
Anyone with information is asked to call Batley and Spen Neighbourhood Policing Team via 101 or to pass information anonymously via independent charity Crimestoppers on 0800 555 111.
