A man has been accused of luring two girls from a city by train and sexually assaulting them, sparking fears there may be more victims.
Queensland detectives are appealing for information after charging the 50-year-old man from Deception Bay over alleged child sexual offences.
Police allege the man approached a 15-year-old girl on June 9 and a 13-year-old girl on June 28 near Roma Street railway station in Brisbane's CBD.
He is accused of then travelling north with the girls by train to Deception Bay - a journey that can take up to 90 minutes.
The offences allegedly occurred at Deception Bay.
Police released body worn camera footage of the man's arrest at a train station.
Officers can be seen boarding a train and speaking to the man before escorting him out on to the platform and arresting him, leading him to a police van in handcuffs.
The man has been charged with multiple child sexual offences and drug offences and will face Caboolture Magistrates Court on July 29.
Detective Acting Senior Sergeant Kate Mitchell said investigators believed there might be more victims and urged anyone with information to come forward.
"The alleged nature and circumstances of this offending are extremely concerning, particularly as we believe there may be other victims who have not yet been identified," Det Mitchell said.
