Another top manager in the frame as Pompey boss Redknapp claims his innocence

The Portsmouth manager was questioned by officers investigating corruption in football at Chichester police station last night before being released on bail.

• Pompey boss Redknapp arrested in Premier League bungs probe
• Redknapp in the net as police put Faye deal under the spotlight
• What Stevens said: extracts from final Quest report (June 15, 2007)
• Those investigated: Redknapp, McKay, Storrie, Mandaric and Faye

He was one of five football figures - along with Portsmouth chief executive Peter Storrie, former player Amdy Faye, ex-chairman Milan Mandaric and agent Willie McKay - arrested on suspicion of conspiracy to defraud and false accounting.

Now the City of London Police force - who specialise in cases of fraud - are understood to have widened their investigations to include a former Premier League boss.

Redknapp insisted last night that he had done nothing wrong and his solicitor Paul Martin, who also represents Storrie, claims the pair were only assisting police with an investigation centred on other people.

He said: "The inquiries do not relate to either of those individuals [Storrie or Redknapp], they relate to entirely different individuals.

"They are ongoing investigations in relation to those other individuals and for that reason they are unable to comment further."

After leaving the police station, Redknapp added: "We all helped the police with their inquiries, but it doesn't directly concern me.

"I've been answering questions to help the police. They have to arrest you to talk to you. I think that's the end of it, it didn't concern me."

A spokesman for Mandaric also confirmed that the Leicester City chairman was asked to assist police enquiries. He said: "While the investigation remains ongoing Mr Mandaric will continue to offer his full support to the police."

The arrests are part of City of London Police's ongoing inquiry into alleged corruption. The men were held as officers carried out raids on 12 locations across the country with Redknapp's luxury home in Poole, Dorset, reported to have been among those searched.

Redknapp was arrested at Gatwick airport as he returned to Britain after watching Rangers' 3-2 defeat by Stuttgart in Germany on Tuesday night in the Champions League.

Police are believed to be examining the transfer of Faye, a Senegal international midfielder, from Auxerre to Portsmouth in 2003.

The fee reported for the player at the time was £1.5million.

The City force's inquiry has been ongoing for some time and a 61-year-old man was held in May on suspicion of money laundering and a 28-year-old man - the Tottenham defender Pascal Chimbonda - was questioned in September.

Police searched Newcastle United, Portsmouth and Glasgow Rangers as well as two homes during a series of raids in July.

When Chimbonda was arrested, the police were understood to have focused their inquiries on the player's move from Bastia in France to Wigan in 2005, for a fee reported at the time of £500,000.

Chimbonda was arrested on suspicion of conspiracy to defraud.

McKay, Chimbonda's agent at the time of his move to Wigan, confirmed in September that Chimbonda had "answered some police questions" but said that the police were "scraping the barrel" with their inquiries.

Chimbonda moved from Wigan to Tottenham for £4.5m in August last year but that move is not thought to be relevant to the inquiry.
