QPR midfielder Joey Barton will face no further action after being arrested for affray last month.

The 29-year-old was involved in a fight with two men outside a nightclub in Liverpool city centre in the early hours of 4 June.

Barton was reportedly on a night out with his girlfriend when the incident took place outside the Garlands nightclub on Eberle Street.

After being arrested, Barton, who lives in Widnes, Cheshire, tweeted: "I got sucker punched in the back of the head."

He added: "Not injured as reported just a small bruise on rear of head/ear.

"I've had worse. Life goes on! Thanks for the concern. Have a good day people."

A picture of the incident, apparently showing a shirtless Barton being held back by police and a woman, was also circulated on Twitter.

A spokesman for Merseyside Police said today: "Merseyside Police can confirm that four men arrested in connection with an altercation in Eberle Street, Liverpool city centre on 4 June will face no further police action.

"The four - two 21-year-olds from Liverpool, a 29-year-old from Widnes, Cheshire, and a 20-year-old from Liverpool - had been arrested on suspicion of affray, and subsequently released on police bail.

"All four have now been notified by the police that, following advice from the Crown Prosecution Service, they will not face any further action."

Barton has a long history of controversy, both on and off the pitch.

In 2008, he was given a six-month jail term after admitting assault and affray during an incident which also took place in Liverpool city centre.

In May, he was given a 12-match ban by the Football Association and fined £75,000 for violent conduct during QPR's defeat at Manchester City on the final day of the season.
