Police have released video footage of a brawl between Watford FC and Derby County supporters.

Fans clashed outside the Tiger Bar, in Lock Up Yard, in Derby city centre on Friday, April 3.

Two groups of men clashed outside the bar after the 2-2 draw between Watford FC and Derby County.

Detectives believe both groups "associate themselves with the respective clubs".

In a highly-contested draw, Matej Vydra put Watford in front midway through the first half before Darren Bent equalised from the penalty spot.

Marco Motta was sent off for the tackle which resulted in the penalty.

Tom Ince put The Rams ahead at the iPro stadium just before the hour mark, but Odion Ighalo sent 2,500 Watford fans into raptures after a cool finished brought The Hornets level with 15 minutes to go.

The game finished 2-2.

Watford were backed by almost 2,500 of their supporters at Derby after the players paid for 18 coaches and the fans returned the favour as they provided vocal backing throughout the game.

Since the incident, football intelligence officers from Derbyshire and Hertfordshire constabularies have been working together to identify the men in the footage.

Several of the men have already been identified and some arrests have been made.

However, officers are keen to trace the five men highlighted in the footage.

Anyone with information should call Derbyshire police on 101, and ask to speak to PC Allan Guy.
