An initial file of evidence on claims Pakistan cricketers accepted cash bribes to take part in spot-fixing during a match has been passed to prosecutors.
Scotland Yard said evidence that there was a conspiracy to defraud bookmakers will be considered by the Crown Prosecution Service (CPS).
Detectives interviewed four players under caution and arrested businessman Mazhar Majeed as part of the inquiry.
Majeed is accused of accepting £150,000 to fix the actions of several players during a Test at Lord's.
A Metropolitan Police spokesman said: "The Metropolitan Police Service has today (September 17) delivered an initial file of evidence relating to conspiracy to defraud bookmakers to the Crown Prosecution Service.
"The file will now be subject to CPS consideration. This is an initial file and the Met investigation continues."
The reputation of the sport was engulfed in controversy over claims of corruption after allegations surfaced in the News of the World newspaper.
Majeed is accused of accepting cash to ask players to deliberately bowl no-balls during their tour of England.
Test captain Salman Butt, Mohammad Asif, Mohammad Amir and Wahab Riaz have all been interviewed under caution.
Butt, Asif and Amir have been suspended by the International Cricket Council (ICC) but deny any wrongdoing. Riaz has not been suspended by the ICC.
