A 60-year-old Sydney man is accused of sending sexually explicit material to a person he believed was a 14-year-old school boy and arranging to meet for sex.
Detectives from the Child Abuse and Sex Crime Squad's Child Exploitation Internet Unit began engaging online with a man from Sydney's south in October.
Police say the man believed he was speaking with a 14-year-old boy and engaged in sexually explicit conversations about acts he wished to perform on the child and sent sexually explicit material.
The man also allegedly arranged to meet the child for sex.
Detectives arrested a 60-year-old man at Westmead on Wednesday.
Police say they seized a laptop and several electronic storage devices when they later searched his home in Gymea.
The man was charged with using a carriage service to procure a child under 16 for sexual activity and using a carriage service to transmit indecent material to a person under 16.
He was refused bail to appear in Fairfield Local Court on Thursday.
