Three people who worked for Nottinghamshire Police have been sacked after being found guilty of gross misconduct.
An information support clerk, based in the city, posted a comment on Facebook which revealed information she had access to.
The 37-year-old was found guilty of breaching the Data Protection Act as well as her professional standards.
A customer service adviser has been dismissed for using the force phone and e-mail systems for unauthorised personal use - neglecting her duty to answer calls from the public.
The 47-year-old, who was based in the force control room, was found to have been making private calls and sending personal e-mails even during peak times for emergency calls.
She also failed to follow the correct procedures for dealing with potentially vulnerable callers, used the force's systems to uncover information without permission, and failed to declare a business interest.
And a constable based at The Meadows, aged 39, was dismissed after making inappropriate and offence comments while being briefed about the police response to a domestic violence incident.
