The girl left the park with the man willingly "thinking she was in the care and custody of somebody... she felt safe with", child abuse and sex crimes squad boss Detective Superintendent John Kerlatec said on Wednesday.
"We will allege that once they left in the car and went to a home at Dural, she was sexually assaulted."
The girl, who cannot be identified, met friends at Hornsby Westfield before going to the skate park and was due to meet her parents at the shopping centre when she failed to return, Detective Superintendent Kerlatec said.
"When she wasn't where she was supposed to be, they [her parents] rightfully raised the alarm."
Detectives were mobilised, with CCTV and what Detective Superintendent Kerlatec called "very thorough and extensive investigation" allowed police to track the man and the girl down at a home in nearby Dural around 1am on Wednesday.
Forensic examiners were going over the home and the vehicle, with the man also being subjected to a forensic procedure at Hornsby police station.
He will face at least four charges on Wednesday with police expecting to lay further charges as the investigation continues, Detective Superintendent Kerlatec said.
The girl was taken to hospital to undergo assessment.
Her parents are "exceptionally distraught", he said.
"We are working closely with the family, the girl is ... being well looked after".
