Largo Fire Chief Mike Wallace is the subject of an internal investigation, though the reasons are not clear, the Tampa Bay Times reports.
The city's HR director, Susan Sinz, who is overseeing the probe, said the investigation could be finished sometime this week, according to the Times. Wallace and other officials declined to comment to the newspaper while the investigation was under way.
As chief, Wallace oversees the department's 134 sworn firefighters and seven civilian employees, according to the city's website.
Wallace, 57, took over as chief in October 2007, the Times reports.
