Cranston Police Chief Marco Palombo Jr. said in statement that he is retiring effective Monday, the same day he was reinstated to his post.
Mayor Allan Fung put Palombo on administrative leave in January when he asked state police to review an alleged parking ticket blitz and the department as a whole. That investigation continues, Fung said.
"This afternoon, I reinstated Colonel Marco Palombo, Jr. for the sole purpose of receiving correspondence announcing his intention to retire as Cranston's Chief of Police, effective today," Fung said in a statement.
Fung said Rhode Island State Police Capt. Kevin Barry will continue to lead the police department until a new chief is named.
Palombo was appointed chief in 2009 and spent 27 years on the force. He said he is most proud of winning national accreditation for the Cranston Police Department in 2012 for the first time in its history.
"Having accomplished the professional goals I set for myself and the department when I was appointed Chief in 2009, I have for some time been considering new opportunities," Palombo's statement said.
Palombo said he would be involved in teaching and training police science and that he would consider private sector opportunities.
