An appeal has been issued by police after a supporter was said to have been knocked unconscious following a Latics game in the West Midlands earlier this season.
Violent clashes were seen between Wigan and Aston Villa fans following their Championship tie on August 11.
One confrontation between rival supporters saw a 57-year-old knocked to the pavement, near Villa Park.
He is then filmed being kicked to the side before order is restored. Another video has also emerged online of Villa supporters descending on a white minibus, packed with what is believed to be Latics fans.
Several men are seen throwing punches at passengers in the rear of the bus.
The 57-year-old suffered head and abdominal injuries. He also had cuts to his arms and legs.
Paramedics treated him at the scene and he was later taken to hospital for further examinations.
A West Midlands Police spokesman said: “We are appealing for witnesses and information and are urging people who may be able to help us to come forward.
