ZACHARY — Saying he was “going to hit the ground running,” David McDavid took the oath of office Wednesday as the city’s new police chief.

McDavid won the remainder of the term begun in January by John Herty, who died in March, defeating acting Police Chief David Courtney and another opponent in the Oct. 22 election.

“We’re going to be seen on the streets; we’re going to be seen in businesses. We want to protect the city and work very hard,” McDavid told well-wishers who crowded into the City Council chambers for the ceremony.

McDavid, 45, served briefly as the department’s assistant chief, then resigned to run for police chief.

“This was a goal and dream of mine, and I’m going to work hard,” he said.

He pledged Wednesday to have a good working relationship with other law enforcement agencies in the area.

During his 27 years with the department, McDavid headed the detectives division, the police dog handlers, the traffic division and communications division.

As the chief detective, McDavid coordinated undercover drug operations in the area.

Before becoming a full-time officer, McDavid was a reserve policeman and volunteer firefighter for the city. He is a graduate of the LSU Basic Training Academy, the FBI National Academy and the Drug Enforcement Administration’s Drug Commander School.
