The 17-year-old pupil was walking home from Outwood Academy Valley Post-16 Centre on Raines Avenue at the time of the incident, which happened yesterday (January 26) at around 3.30pm.
After “exposing” himself to the teenager, the man followed her in his car onto Prospect Drive where she managed to escape onto the estate before running home.
It comes after an Outwood Academy Portland pupil was followed home by two men in a car on January 13, though police say there is “nothing to suggest” there is a link between the two incidents.
A spokesman for Nottinghamshire Police confirmed that enquiries into the incident were ongoing.
“Anyone with information about the incident should call 101, quoting incident number 534 of 26 January,” they added.
