The Championship side confirmed today that the former Premier League attacker has been detained in relation to offences, but it remains unclear as to whether or not the 32-year-old has been involved in any illegal activity.
The problem is believed to relate to overseas betting syndicates – mainly from Asia – who are thought to be operating unlawfully in the English game.
The National Crime Agency (NCA) are investigating a spot-fixing problem which has become a major talking point after The Sun reported that Sam Sodje allegedly received £70,000 to get himself sent off.
In the report, the former Portsmouth man is said to have claimed he could rig top tier games and that plans were afoot to influence ties in next summer’s World Cup.
The extent of the problem is unclear, and it is unknown as to whether any top tier matches have been the subject of illegitimate actions.
England would not be the only nation to be hit by match fixing concerns, with the Italian top tier perhaps the most famous example of such problems in recent memory.
