KEY POINTS:
Birmingham City directors David Sullivan and Karren Brady were arrested yesterday as part of a police investigation into corruption in English soccer.
City said the Premier League club's co-owner Sullivan and managing director Brady "were invited to co-operate with a City of London Police investigation and have happily done so".
Previous arrests include Harry Redknapp, manager of FA Cup finalists Portsmouth, in November. He has always insisted that he has done nothing wrong and he has not been charged.
Clubs investigated last year include Newcastle United and Scottish league leaders Rangers.
