Greenville Police Chief Hassan Aden is leaving the department after just two years.
Aden will take a job with the International Association of Chiefs of Police in Washington as head of research, programs and professional services.
During a noon news conference at city hall, Aden said it was sad for him to leave Greenville, saying it was a very difficult decision.
Officials said the chief's last day will be January 12th. Mayor Allen Thomas says Deputy Chief Ted Sauls will be the department's interim chief.
Aden took on the role of chief in November of 2012 after Chief William Anderson left for a new job in Asheville.
The chief admitted it was a little premature for his departure, and that he did not plan on leaving Greenville this quickly.
Before coming to Greenville, Aden worked for 25 years for the Arlington, Virginia Police Department. He left as deputy chief.
