The siblings were stopped by police in the early hours of the morning, according to the Alachua County Sheriff's Office.

The pair had travelled for more than three hours, from the city of North Port to Alachua.

Police stopped the car, which had been reported stolen, at about 4am.

They were "much surprised" when two children stepped out, according to a Facebook post from the sheriff's office.

The officers then learned the children had been reported missing.
