ROCHESTER, N.Y. (AP) — An upstate New York police chief is leaving his position to take a role in the U.S. Drug Enforcement Administration.

Rochester Mayor Lovely Warren announced Tuesday Chief Michael Ciminelli will resign Sept. 15. He had served as police chief since March 2014.

Deputy Chief Mark Simmons will serve as interim chief. Simmons has been with the department for 16 years.

Ciminelli said in a statement he was grateful for the opportunity to serve Rochester. He added that he's looking forward to the opportunity to "serve at the federal level."

The announcement comes a week after two Rochester police officers were suspended without pay following allegations of excessive force. The Monroe County District Attorney's Office is investigating the incident.
