Three Boston police officers are on administrative leave while the department investigates suspected payroll violations, according to a department spokesman.

Officers Louis A. Vasquez, David A. Stewart and Curtis Carroll, who were assigned to the front desk at headquarters, are currently under investigation by the department’s internal affairs unit and are on leave, said BPD spokesman Detective Sgt. John Boyle.

“The officers have been placed on administrative leave pending an ongoing internal affairs investigation into time and attendance issues,” Boyle said in a prepared statement. “Since the investigation is ongoing and not concluded at this time, no decision on further action by the department will be made until the internal affairs unit has completed its investigation.”

Boyle declined further comment Monday night.

Each raked in more than $150,000 in total pay, according to city payroll records. Vasquez was the highest earner with $244,297, adding more than $107,502 in detail pay and $25,617 in overtime to his $92,741 base pay. Carroll brought home $200,134 — $95,390 in base pay plus $23,744 in overtime and $60,582 for detail work. Stewart earned $150,120, including $28,116 in overtime and $15,686 in details on top of his $103,890 base.

A police union lawyer for the officers could not immediately be reached for comment. None of the three men could be reached for comment.

The Suffolk County District Attorney’s office said no charges have been filed against the three.

This BPD investigations comes amid an ongoing unrelated scandal surrounding state police, in which multiple troopers have been charged with abusing their work hours by fudging overtime logs or simply not showing up.
