Scotland Yard has said it has passed on to prosecutors an initial file of evidence on claims that Pakistan cricketers were involved in spot-fixing.

It said evidence that there was a conspiracy to defraud bookmakers will be considered by the Crown Prosecution Service (CPS).

"The Metropolitan Police Service has today delivered an initial file of evidence relating to conspiracy to defraud bookmakers to the Crown Prosecution Service," a Scotland Yard spokesman said. "The file will now be subject to CPS consideration. This is an initial file and the Met investigation continues."

Four Pakistan players - Salman Butt, Mohammad Asif, Mohammad Amir and Wahab Riaz - have been questioned by the police, and the first three have been suspended by the ICC pending the investigation. Those three have returned to Pakistan following an agreement with Scotland Yard that they would return at any time for further questioning.

Butt, Asif and Amir have also replied to notices issued to them by the ICC after it felt they had a case to answer.

Scotland Yard's announcement comes a day after ICC president Sharad Pawar said the police investigation was "likely to end soon".
