Figures show overall drop in complaints about police
Almost 3,000 complaints were made about police officers in Northern Ireland last year.
A total of 2,797 issues were raised by the public in the 12 months to April - down 8% from the previous year.
The figures emerged in a report by the Police Ombudsman's Office.
Belfast City had the largest decrease in complaints, where numbers fell by 19%. Derry City and Strabane had a drop of 13% in the numbers of complaints about its officers.
Mid and East Antrim had the largest increase in complaints - up by 17%, though this may have been due to events connected to the environmental protest at Woodburn Forest near Carrickfergus.
Not all complaints were subject to a full investigation. Last year more than 100 complaints were judged to be ill-founded and without basis or foundation.
