Complaints against three North East police forces rose over the last year. Durham Police received 54% more allegations against officers, Cleveland 15% more, and Northumbria 6% more.
The figures, from the Independent Police Complaints Commission, showed the total number of complaints against each force in 2011/12, and the number of separate allegations.
When the figures were adjusted for the size of the force, Cleveland Police had the highest number of allegations in the country, followed by North Yorkshire Police.
- Cleveland: 378
- North Yorkshire: 318
- Northumbria: 209
- Durham: 198
- (Figures show allegations per 1,000 personnel.)
However, the report suggested the forces with the highest number of complaints and allegations could be due to officers making it easier for people to come forward.
Chief Inspector Steve Winship, of Durham Police, said he thought people had confidence in his force.
"Historically, Durham's figures have been really low and there is no doubt that there has been an increase this year. I do not see that as a bad thing.
"I think it is about the confidence that the community has in Durham Constabulary; about having confidence that we will investigate things properly and hopefully quickly where necessary."
