( AFP ) - Police questioned Portsmouth manager Harry Redknapp and four others Wednesday as part of an investigation into alleged corruption, the English Premier League club said.
One of the other five men arrested Wednesday was the club's chief executive, Peter Storrie.
Following his release later Wednesday, Redknapp said he had helped police with their enquiries and he thought that was the "end of it".
Along with Redknapp, three of the other man were released on Wednesday evening, a City of London spokeswoman told AFP.
"We all helped the police with their enquiries, but it doesn't directly concern me, it's other people involved," Redknapp said after returning to his home in Dorset, on the southern English coast.
He also confirmed that along with him and Storrie, former Portsmouth owner and Leicester City chairman Milan Mandaric had also been arrested.
"I've been answering questions to help the police," said Redknapp. "I am not directly concerned with their enquiries.
"They have to arrest you to talk to you, for you to be in the police station. I think that's the end of it, it didn't directly concern me."
Redknapp's lawyer Paul Martin, who is also representing Storrie, stressed that the pair were co-operating with police. He reiterated Redknapp's comments that the enquiries were to do with other individuals.
"Portsmouth Football Club can confirm that chief executive Peter Storrie and manager Harry Redknapp have today been asked to help police with their inquiries concerning a matter dating back to 2003," an earlier statement from the club read.
"This was prior to the new owner (Alexandre Gaydamak) taking control of the club at the beginning of 2006. The club is fully supportive of Peter and Harry, who are co-operating fully with City of London Police in this ongoing inquiry.
"Both are playing major roles in the continued success of Portsmouth Football Club."
City of London Police said earlier that they had detained five men aged 30, 48, 55, 60 and 69 on suspicion of conspiracy to defraud and false accounting as officers swooped on eight addresses across Britain.
Of them, only the 30-year-old remained in police custody on Wednesday evening, with the other four having been released on police bail, according to the police spokeswoman.
The force's economic crime unit is looking into alleged bribery in the British game. It is one of a number of such probes in recent years.
Former Scotland Yard chief John Stevens has been holding a separate inquiry into alleged irregular transfer payments in the Premier League.
The City of London Police, which takes the lead in fraud investigations around Britain, launched its investigation in late 2006.
In June 2007, Stevens, formerly Britain's top police officer, presented a report to the Premier League identifying 17 transfers as suspect.
He concluded there was no evidence of illegal payments to club officials or players and said all the clubs named had fully co-operated with his investigation.
In September 2006, undercover filming for a BBC television documentary appeared to suggest that Redknapp, 60 was discussing an illegal approach to a player. He denied anything untoward.
South coast club Portsmouth, under Redknapp's guidance, are currently an impressive sixth in the table having just missed out on qualifying for European competition last season.
