Three Derbyshire police officers and two civilian staff have been sacked for illegally hacking the police database, according to figures released this week.
A Freedom of Information request by watchdog Big Brother Watch revealed that Derbyshire Constabulary had the fifth highest number of staff sacked for Data Protection Act breaches in England.
A total of 11 police and four civilians were internally disciplined for data protection offences in the three-year period the data covers from 2007 to 2010.
The report said 904 police officers and support staff across the country have been disciplined for abusing their access to confidential systems, 243 have received criminal convictions for their actions, and 98 have lost their jobs.
Some of those disciplined were found to have used the police database to look up family, friends and even neighbours.
