After investigating the complaints, police officials said nine were cleared and the rest were addressed either with additional training, employee counseling or other disciplinary action.

During that same period, the department received 63 written letters of commendation and “numerous” telephone calls from people who appreciated the department’s work in the community, police said. On the 2010 Citizen Satisfaction Survey, residents expressed an overall satisfaction rate of 95.5 percent. I n fiscal 2011 the department had about 120 employees.

“I am very pleased with the small number of complaints received given the thousands of citizens,” Manassas Police Chief Douglas W. Keen said. “The extremely low number of complaints…are a direct indiction of the professionalism and dedication to service of all of our employees, whether sworn or civilian.”

In 2010 the department recorded almost 55,000 calls for service, which resulted in 1,900 arrests, 5,670 traffic summonses and almost 6,000 parking tickets, police said.
