Two "young females" were followed by a man with a mohican in Ollerton.
Police are now appealing for information about what they are describing as a "suspicious" incident.
Two "young females" were walking from Church Circle to the play park on Whitewater Road when "they became aware of a vehicle that was travelling slowly and appeared to be following them".
A spokesman for Nottinghamshire Police's Sherwood neighbourhood policing team, said: "The vehicle is described as a white Transit-size van with no markings.

"The males made no attempt to speak to the girls or to exit the vehicle.
"At this stage it is a suspicious incident and any information with regards to the van or its occupants can be reported on 101 quoting incident number 000401-27012019.
"Anybody in the vicinity at the time may remember the vehicle travelling the wrong way around Church Circle."
