The Reading Fire Department is once again without a chief following the sudden departure of David Hollinger.
Hollinger on Monday submitted his letter of resignation to Mayor Vaughn Spencer, who told 69 News that he accepted it with regret and thanked him for his service.
"Chief Hollinger's service to the city is appreciated and I wish him the best in all his future endeavors," Spencer said.
Hollinger, who officially became chief on June 1, 2012, had come under fire from the department's rank-and-file members in recent months.
The firefighters' union took a no confidence vote in March, with members agreeing that Hollinger was unfit for the job.
The firefighters then laid out several of its complaints for City Council, including claims that Hollinger belittled the department's deputy chiefs and lied on a FEMA grant application.
Hollinger, a Reading native, came back to his home city after retiring as a fire lieutenant in Washington, D.C., and serving a brief stint in fire protection with the Dover International Speedway and Dover Downs Casino and Hotel in Delaware.
69 News has not been able to reach Hollinger for comment.
