Customs investigators have made three more arrests in connection with the Pakistan spot-fixing investigation, Cricinfo has confirmed.

"Two men and a woman, all from London, were questioned yesterday as part of an investigation into money laundering before being released on bail," HM Revenue and Customs said in a statement.

The arrests are understood to be part of a line of enquiry that is separate to the Lord's spot-fixing scandal. Customs confirmed that "two 35-year-olds (a male and a female) from the Croydon area and a 49-year-old male from the Wembley area" had been arrested, adding: "These individuals were arrested, questioned and have been bailed pending further investigations."

The developments come as it was revealed that Salman Butt, Mohammad Amir and Mohammad Asif, the three Pakistan players whose mobile phones were confiscated in the wake of the News of the World revelations, would be returning to London for talks with the PCB chairman, Ijaz Butt.

However, despite intense pressure from the ECB to drop the three players, Butt told Cricinfo on Monday night that there would be no changes to the squad. "There is a case going on with the Scotland Yard," he said. "This is only an allegation. There is still no charge or proof on that account. So at this stage there will be no action taken."
