The ICC is investigating alleged corruption in Sri Lanka, which centres around a taped conversation.
A recording of the conversation had been given to a Sri Lankan media organisation, and SLC on Thursday.
SLC then passed the tape on to the ICC's Anti Corruption and Security Unit, currently in the country for the SLPL.
The anti-corruption measures for the SLPL are identical to those implemented for international matches.
Two members of the anti-corruption unit will be in Sri Lanka for the duration of the tournament.
