A New South Wales police officer has been charged with making an offensive call to federal Greens senator Sarah Hanson-Young.

Australian Federal Police allege the 56-year-old Senior Constable called an Australian senator in July.

He was charged with one count of using a carriage service to menace, harass or offend after AFP officers searched his home in south-west Sydney.

NSW Police will review the employment status of the officer, who is attached to the Central Metropolitan Region.

He is due to face court in November.

Senator Hanson-Young said she received a number of threats during the public debate over comments senator David Leyonhjelm made about her.

"One of these was particularly distressing as it involved my daughter," she claimed.

"It is now a matter before the court and, as such, I won't be commenting further."

Senator continues to fight in defamation suit

Senator Hanson-Young is embroiled in a defamation suit against Senator Leyonhjelm, accusing him of attacking her character and causing her "considerable harm" in statements he made about her views on men.

The dispute was prompted by a parliamentary debate about violence against women, in which the Greens senator alleged Senator Leyonhjelm told her to "stop shagging men".

When he refused to withdraw those comments and he went further into his criticisms in media interviews, she accused him of "slut shaming" her.

ABC reported last month the Greens senator offered to settle the case if Senator Leyonhjelm paid her $75,000 and issued an apology.

He refused and said he would continue to fight the defamation case and dismissed her claims as a publicity stunt.
