A former Ipswich Town player is one of six arrested by the National Crime Agency following an investigation into claims of match-fixing in the Championship.

Blackburn Rovers have confirmed that DJ Campbell, who came to Town on loan in 2012, is one of those arrested.

Today’s Sun has further claimed that a tackle made by the striker, who now plays for Blackburn, against Ipswich defender Aaron Cresswell in the Championship fixture at Portman Road last Tuesday could be one of those under scrutiny by police.

Campbell, 32, received a yellow card in the 23rd minute for his challenge on Cresswell.

The £20,000 a week former Premier League star has played for Birmingham, Blackpool and QPR.

Campbell came to Ipswich Town on loan from QPR in October last year for three months.

He scored in his debut game against Cardiff City and went on to score 10 goals in 17 appearances for the side.

This morning a spokesman for Blackburn Rovers FC said: “Blackburn Rovers can confirm that striker DJ Campbell has been arrested.

“The club will be making no further comment on what is now an ongoing legal matter.”

Over the weekend the National Crime Agency arrested six people on the basis of information passed to them by the Sun on Sunday.

The tabloid reported that an undercover investigator met ex-Portsmouth player Sam Sodje, who allegedly said he could arrange for footballers in the Championship to get themselves a yellow card in return for tens of thousands of pounds.

The 34-year-old also reportedly claimed he could rig Premier League games and alledgedly said he was preparing to fix matches at next year’s World Cup in Brazil, the newspaper reported.

Richard Bevan, chief executive of the League Managers’ Association, said the organisation had debated match-fixing on previous occasions.

“What is important is that The FA, Premier League and Football League continue to make sure our game is continuing to move forward,” he said.

“Whether it is cricket or football all around the world there are issues in this 24/7 internet and social media world that puts a lot of pressure on.

“There needs to be really strong leadership at the top.”

Responding to the claims about Sodje yesterday, Portsmouth FC spokesman Colin Farmery said: “If these serious allegations are true then we are extremely shocked and saddened by them, as match-fixing of any type goes to the heart of the integrity of the game.

“The player in question no longer plays for the club and we have not been contacted by the authorities, but of course we would cooperate fully with any inquiry.”

It was also reported that Oldham Athletic player Cristian Montano failed to get a yellow card in return for money in a match against Wolverhampton Wanderers on October 22 and offered to take part in another rigging incident .

Oldham said in a statement: “Oldham Athletic Football Club has been made aware of the incident and allegation surrounding one of its players, Cristian Montano. The club will commence an immediate internal investigation to establish all the relevant facts of the case.

“The club is co-operating with other agencies in this matter and cannot comment on specific facts at this stage. The club will not be issuing any further statements at this time.”

One of those arrested yesterday remains in custody.

The National Crime Agency said: “The NCA can confirm that the Sun on Sunday has passed material from its own investigation to the National Crime Agency.

“An active NCA investigation is now underway and we are working closely with the Football Association and the Gambling Commission. Five people were arrested on Sunday morning, and bailed that evening until April 2014. A sixth individual was arrested on Sunday evening and is being questioned by NCA officers.

“No further detail is available at this stage.”
