Trouble broke out at a train station last night sparking a major police response.

There was a sea of blue lights outside Watford Junction at around 11pm following reports of football fans fighting on the platforms.

Supporters of both Watford and Burnley were said to be involved following their teams' Friday night Championship fixture at Vicarage Road.

One Watford fan told the Observer there were around 200 fans in the station on different platforms when trouble started.

Fans reportedly climbed onto or ended up on the tracks.

Once officers arrived, a video showed one person being restrained by officers on the ground.

Officers from the British Transport Police and Hertfordshire Constabulary attended with police dogs also called in to try and control the situation.

It's unclear whether anyone was injured.

At least one arrest was made in relation to trespassing on the tracks.

Hertfordshire Constabulary's Specials unit, which is made up of part-time and voluntary officers, tweeted just before midnight: "Watford Specials assisted this evening at Watford Junction with disorder occurring on the platforms.

"One male arrested for trespass on the railway #stayoffthetracks."

Watford won the game 1-0 thanks to a goal from Tom Cleverley, sending the Hornets top of the table ahead of the rest of the weekend's games.
