Melbourne, Hosier Lane: Man, 37, hands himself into police after young girl was saved from a terrifying alleged abduction by Good Samaritan

A 37-year-old man has turned himself into police just one day after a 14-year-old schoolgirl recalled how she was saved from a harrowing alleged abduction attempt.

The Melbourne girl joined police in a public appeal on Wednesday to find her alleged attempted abductor following an almost month-long search.

It's alleged the teenager was approached by an unknown man while on a class excursion of the city's grafitti laneways.

She had fallen behind the group and was on Hosier Lane when the stranger approached and called her 'pretty'.

Police allege the man then grabbed the girl's arm and attempted to drag her further down the lane.

Fortunately, another stranger saw the teenager's distressed and stepped in, pretending to be her teacher.

A 37-year-old Thornbury man presented himself at a police station on Thursday in relation to the case.

Police said in a statement the man 'is currently assisting police with their inquiries'.

More to come.
