Police have spoken to the man who allegedly made an ''unwanted advance'' towards a female hitchhiker he picked up in Central Otago on Monday.
The 22-year-old hitchhiker was picked up near the cemetery in Frankton by a man driving a fawn 4WD.
She was later dropped off in Cromwell.
It was alleged the man had touched her inappropriately.
Yesterday, police said they had spoken to several witnesses and, as a result, had been able to identify the driver of the 4WD vehicle involved.
''Police are grateful to the public for providing information,'' a police spokeswoman said.
''Police have spoken to the man this afternoon and will continue to speak to a number of other people in coming days as their inquiries continue.''
Hitchhiking or accepting rides from strangers, was not recommended, police said.
''If you do decide to hitchhike, police strongly advise you not to travel alone.
''Make sure there is always someone who knows where you are going and when you should arrive at your destination.
''An option for hitchhikers is to use the Safe programme run by Spark, which allows people to record the vehicle they get into, the time of travel and travel route.''
