Two Boston police supervisors have been placed on paid leave pending an ongoing investigation into overtime and payroll abuse that has already targeted other officers, according to the department.

Detective Sergeant John Boyle would not identify the officers, but said Friday that they were supervisors assigned to the department’s evidence management unit and had been placed on leave Feb. 15. He said the matter is being investigated by the department’s internal affairs unit and also has been referred to the Suffolk district attorney’s office. A spokesman for the district attorney declined to comment on the case Friday.

Boyle said in a prepared statement that the investigation centers on what he called an administrative issue, and the department is confident that the integrity of the evidence stored in the evidence room was not compromised.
