At least 20 NSW Police officers have been charged with criminal offences so far this year, with accusations ranging from creating false documents to importing pepper spray and sexual assault.

Seven of the officers charged were male senior constables and the rest were of lower rank. Only three of the charged serving officers were women.

One officer is expected to face court after he was recently charged with the aggravated rape of a 10-year-old girl and assault occasioning actual bodily harm.

The 40-year-old senior constable was given a court attendance notice at work and was expected to appear before Goulburn Local Court on June 19.

An interim apprehended violence order was in place to protect the alleged victims and witnesses, police said. The constable has been suspended from duty with pay pending the outcome of his case.

On Wednesday, a police officer from Sydney's west will face court after he allegedly made threats against a private business on the telephone. The senior constable, 38, is expected to appear before Downing Centre Local Court charged with using a carriage service to threaten serious harm.

Of the more serious alleged incidents, one senior constable was charged with five counts of sexual assault and four of common assault after a series of domestic-related incidents in the state's west in February.

A female probationary constable was charged in February after she was allegedly caught importing pepper spray into Australia.

Another officer was before the courts charged with attacking a woman during an argument on the way home from a New Year's Eve party. He was charged with causing grievous bodily harm with intent and granted bail before his expected appearance at Newcastle Local Court.

A NSW Police media spokesman said it was always a concern when a police officer was charged with criminal offences. ''No police officer is exempt from the law,'' he said. ''The fact that officers are charged and put before the courts is an indication NSW Police officers are not above the law.

''Further, the NSW Police Force issues a media release whenever an officer is to be put before the courts in the interests of transparency. Officers who lose the commissioner's confidence are dismissed from the organisation.''

In the 2012-13 financial year, NSW Police Commissioner Andrew Scipione dismissed four officers under section 181D of the Police Act, which can be brought into effect if the commissioner loses confidence in the police officer's suitability to serve.
