Police Constable Amanda Aston, 43, was found guilty of two counts of perverting the course of justice and one count of fraud by false representation following a three-week trial at Maidstone Crown Court.
During the trial, the court heard how Aston, who was based at Guildford police station, had embarked on a relationship with another officer in February 2017.
During their relationship, she reported to colleagues that she had been the victim of domestic abuse, making false allegations of control and abuse about him.
He was charged with engaging in coercive and controlling behaviour. He was further arrested after breaching his bail conditions not to contact her and served two months in prison as a result.
However, evidence later emerged which indicated that Aston had withheld key information and misled the original investigation team by providing false statements which led to him being arrested and charged.
Chief Superintendent Tom Budd said: “Criminal offences committed by our officers and staff simply cannot be condoned. Allegations against any of our officers or staff are always subject to a thorough investigation to ensure that those who do not meet the high standards expected of them to in order to maintain public trust and confidence are dealt with swiftly and robustly.”
Aston will be sentenced on 22 May at Maidstone Crown Court.
