The corruption probe which led to the arrest of Birmingham City FC executives Karren Brady and David Sullivan is focusing on payments to a football agent and two players, the club said today.
Shares in the club were suspended on the London Stock Exchange earlier today after it emerged that managing director Brady and co-owner Sullivan had been interviewed by police.
The club today confirmed that the investigation relates to transfer payments during the 2002/03 season.
The club issued a statement today which read: "The City of London Police investigation is focusing on payments to a football agent and two players, dating back to 2002/03.
"There is absolutely no allegation that any director of the [plc] company or the club itself have benefited financially from any of this activity."
The statement added that the activity was not considered material to its financial affairs and were in relation to PAYE and National Insurance contributions.
The club reiterated that it was co-operating fully with the police, concluding: "We wish to make it plain that David, Karren and Birmingham City FC deny absolutely any wrong doing."
