NSW man charged over online grooming

A NSW man is in custody facing accusations of using social media to groom children aged between 12 and 17.

The 25-year-old will face court on Wednesday after an investigation into child-grooming offences led to his arrest.

Wollongong police say they received information which led them to search his home on Monday and seize his devices.

He faces nine criminal charges, including seven counts of using a carriage service to menace, harass or offend.
