NSW Cop Who Worked With Kids Charged With Child Sex Offences

A Sydney police officer tasked with warning school children about the dangers of online predators has been charged with sexually abusing and raping a child over a 10-year period.

The victim was aged under 10 when the alleged abuse began.

Senior Constable Dean Perkins, 43, visited school across Sydney's west in his role as the force's youth liaison officer.

He would tell children how to protect themselves from cyberbullies, sexting and online predators, one school's newsletters reported.

He also met with P&C groups and appeared on "anti-bullying plans" for multiple schools as a contact point for children and parents seeking further information.

But detectives allege Perkins was a wolf in sheep's clothing who, between 2007 and 2018, was sexually abusing a child.

He was arrested on Thursday after an internal investigation by the professional standards command supported by the child abuse and sex crimes squad.

He's been charged with aggravated indecency and assault, attempted sexual intercourse with a child under 10, grooming a child younger than 14 for sex, two counts of sex with a child aged 10 to 14 and peep or pry.

He was suspended from duty as a result, NSW Police said in a statement on Friday.

He was refused bail at Penrith Local Court on Friday, but his lawyer Richard Waldersee expressed strong concerns for his safety.

"He's had major threats in jail," Waldersee said.

"Everybody in custody suffers. And if you go in as a copper, with that sort of thing alleged against you? You suffer."

He also confirmed that Perkins will be pleading not guilty to all charges.
