Police say they have arrested people in Somerset and Bristol after Legia Warsaw football hooligans clashes with officers after violence broke out ahead of their game with Aston Villa.

Polish fans set a police officer on fire and injured four others, two police dogs and two police horses when the ugly scenes erupted outside Villa Park last year.

Dozens of arrests were made following the carnage, which broke out ahead of the Europa Conference League game on November 30.

West Midlands Police described the major disorder as the "worst violence seen in 28 years of policing" at a football match.

The force has now released never-before-seen footage of the chaos which marred the game and led to Legia supporters being banned from entering the ground.

Burning flares, bricks and bottles were hurled towards cops by the car park reserved for away coaches along Witton Lane.

Detectives are now appealing again for the public's help in tracing four men still wanted in connection with the disorder after previously charging 46 others.

Detective Sergeant James Birtles said: "The disorder that happened that evening was absolutely horrendous.

"We've spent hundreds of hours watching CCTV, body worn video and drone footage, and taken hundreds of statements from officers about the violence they faced.

"Since the disorder, we've made three more arrests, in Bristol, Somerset and Leicester.

"Those men have been bailed while we liaise with the Crown Prosecution Service and seek charges."

Police said fans were contained and dispersed when tickets were not distributed by the away club to supporters outside the ground, as had been anticipated.

This led to "90 minutes of sustained violence" by Legia fans and the latest footage shows the riot-like scenes that unfolded in a car park used for away fans.

PC Andrew Forbes, 43, was set on fire when he was hit by a flare, which got stuck in his uniform.

His colleagues managed to put out the flames and he was rushed to hospital with burns and smoke inhalation.

PC Forbes, who has served in West Mercia Police for 20 years, said previously: "I'm thankful that my kit and training stood the test and I have an overwhelming relief that I didn't receive any injuries that will be everlasting.

"That certainly outweighs the 'ifs, buts and maybes'."

Four men are awaiting trial for offences including violent disorder and assaulting an emergency worker.

One man arrested on the night has already been convicted of possessing drugs, while another was convicted of carrying a knife and given a four-year football banning order.

No home fans were arrested and police said there were no issues from Aston Villa supporters at any point.

Villa won the game 2-1 and have since gone on to reach the quarter finals of the competition.
