The Crown Prosecution Service has been given a second file of evidence concerning claims that Pakistan's cricketers took bribes to involve themselves in spot-fixing during the fourth Test against England at Lord's in August.
Scotland Yard said that proof that there was a conspiracy to defraud bookmakers will be looked into by the CPS, although the investigation continues to unfold.
Detectives interviewed four players, three of whom - Salman Butt, Mohammad Asif and Mohammad Amir - are currently suspended from international cricket by the ICC and have lost their central contracts by the Pakistan Cricket Board as well.
Mazhar Majeed, a businessman and players' agent, was taken in as part of the investigation, and has been accused of accepting £150,000 to fix the actions of many players in the Lord's Test.
A Metropolitan Police spokesman told reporters: "The Metropolitan Police has today delivered a second file of evidence to the Crown Prosecution Service (CPS) in connection with the investigation of alleged offences in relation to the fourth Test at Lord's Cricket Ground on 26 August. The file will now be subject to CPS consideration."
The ICC's code of conduct commission declined appeals by Butt and Amir against their suspensions last Sunday, while Asif had withdrawn his appeal. The next phase will be a hearing by the anti-corruption tribunal into details of the spot fixing case.
