Complaints against Lancashire Police rose by 13% in 2009-10, the Independent Police Complaints Commission (IPCC) has said.
The force had 947 complaints compared to 836 in the previous year.
Of those, 226 were allegations of assault, 494 were about neglect of duty and 347 were about "incivility", the IPCC said.
Lancashire Police said their more recent figures showed a drop from April to December 2010.
'Act on feedback'
Det Supt Martyn Leveridge said: "Whilst these figures for 2009-10 show an increase in the total number of complaints against the police in Lancashire, our most recent figures show that these have fallen by almost 13% from April 2010 to December 2010 and that more than 88% of people are satisfied with the overall service they receive.
"Delivering a high quality service is a priority for us and we will continue to actively encourage people to let us know if they are unhappy with the service they receive.
"We are committed to acting on constructive feedback from the public and take every complaint as an opportunity to make improvements.
"We are also focusing on reducing the time it takes us to deal with complaints.
"Our ultimate aim is to provide the best possible service we can to the people of Lancashire."
In England and Wales, 33,854 people complained about police - a rise of 8%.
Len Jackson, interim chair of the IPCC, said: "The number of 'rude and late' complaints highlights the standards expected of the police service and the need to improve how they interact with the public.
"However, while some aspects can be improved without cost, such as through better leadership, smaller police budgets will present a challenge around levels of service and public expectation.
"This will require forces to develop an open dialogue with the public."
