Supreme Court judge Njoki Ndung'u will record a statement on Tuesday over allegations of corruption.
DCI George Kinoti on Saturday told the Star this was done after a request made by her lawyers in a letter dated March 21.
In the letter, her advocate Andrew Musangi said Ndung'u was prepared to record a full statement at the DCI offices.
This was after a petitioner Jared Ngeri accused Ndung'u of engaging in corruption and wanted her removed from her post.
"Our clients takes the allegations against her extremely seriously. These allegations suggest criminally culpable conduct on the part of the judge," Musangi said.
Musangi said the allegations against Ndung'u need to be investigated notwithstanding the Judicial Service Commission proceedings.
"While maintaining her innocence ... our client strongly believes that it is important that any criminal investigation against her is investigated," he said.
The lawyer asked the DCI to immediately and thoroughly investigate all the allegations of improper communications between Ndung'u and any of the stated persons in the petition including but not limited to accessing all relevant telephone records from all service providers.
"Investigate all alleged leakage of the judgement of the Supreme Court to any nonauthorised party," he said.
"Investigate all comments on the judgement prior to delivery to determine if they were borne of corrupt practice or any other criminal breaches."
The Judicial Service Commission began hearing petitions filed against 11 judges, including Ndung'u.
Most of the petitions were filed in January, but the commission was not able to deal with them because it did not have a quorum.
