A 33-year-old Sydney man who was using the internet to find and groom teenage girls has been arrested.

A Sydney man trying to groom teenage girls in order to have sex with them has been arrested after an online police sting.

The 33-year-old man from Baulkham Hills was arrested after officers from Queensland’s Sex Crimes Squad’s Child Exploitation Internet Unit pretended to be a mother and her teenage daughter.

The man allegedly made a number of sexually explicit comments about having sex with the teenager over the phone and in SMS messages.

After he arranged to meet whom he believed to be the mother and daughter, Queensland Police passed the information onto their NSW counterparts who made the arrest on Tuesday.

The man was charged with one count of using a carriage service to procure persons under 16 years for sexual activity, one count of using a carriage service to send indecent messages to a person under 16 and three counts of using a carriage service for child pornography.

He was granted conditional bail and will appear Fairfield Local Court on October 20.
