The top CHP officer in Sonoma County, Capt. Greg Tracey, has been relieved of his duties while the agency conducts an investigation into issues that include his management practices, say several law enforcement sources.
Tracey, 54, was placed on administrative leave March 8.
Complaints have included allegations of favoritism, threatening and retaliatory behavior.
As head of the California Highway Patrol's Sonoma County office, Tracey is akin to a police chief and oversees the third-largest law enforcement agency in Sonoma County.
Napa CHP Capt. Chris Childs currently is filling Tracey's position as commander of the office in Rohnert Park, CHP spokeswoman Diana McDermott said.
CHP officials Tuesday said Tracey remains a state employee but would not confirm whether he is on leave or the subject of an investigation, citing state personnel regulations.
Calls to the Rohnert Park office regarding the new management were directed to CHP officials at the Golden Gate Division office in Vallejo, which oversees the Sonoma County office.
"At this time specifically, Capt. Tracey is not the subject of a criminal investigation," said McDermott, public information officer for the Golden Gate Division. "And we are restricted by state law on commenting on whether any employee is the subject of an internal investigation."
McDermott also would not say why Tracey was not working at the Rohnert Park office, where he had been commander since December 2010.
"He's been given direction by his superiors and what this specifically is, I don't have that available," McDermott said.
