A married police community support officer accused of using the criminal intelligence system "as a dating agency" to strike up affairs while on duty has been found guilty of misconduct.
Peter Bunyan, who worked for Devon and Cornwall Police, was found guilty of one count of misconduct.
Jurors deliberated for nearly four hours before returning a unanimous guilty verdict at Taunton Crown Court. They retired for the weekend and will resume their deliberations on 11 further counts on Monday.
Father-of-two Bunyan, 40, is alleged to have accessed highly sensitive police data to perform background checks on women and their former partners after so-called "welfare" visits to victims of crime.
He is accused of neglecting his duties by turning his police radio down on shifts before having sex with women, including at a police neighbourhood office, as well as encouraging one mentally ill woman to send "soft porn" pictures of herself on e-mail to the police station.
Bunyan denies all counts of misconduct in a public office, taking place over a five-year period in the Camborne and Redruth areas of West Cornwall.
Bunyan admits having sex with four women, but said it was while he was off duty. He denies sex with a fifth woman. He admits having sex with one of them while on duty, but said that this was not misconduct – he said he was merely being negligent.
Bunyan's counsel, Michael Melville-Shreeve, argued on Thursday that, although his client might be "a rat" and "a disgrace", he was not a serious criminal.
He said: "If it's not serious crime [for an on-duty police officer] to have tea with someone for half an hour, it is not a crime to have sex consensually with them."
