Police hunt 'suspicious' motorist in Central Scotland
Police are trying to trace a motorist who tried to persuade two women to get into his car then was seen acting suspiciously by a 13-year-old girl.
The three incidents, which involved a man in his 40s or 50s driving a grey or silver car, are thought to be linked.
The driver may have been bitten by a dog during the second incident, when he approached a 39-year-old woman in Grangemouth on 14 July.
The other incidents took place in Alloa and Alva over the past four weeks.
The driver tried to strike up a conversation with a 17-year-old girl who was walking in Hilton Road, Alloa, at about 1300 BST on Tuesday 22 June, but drove off when she refused to get into his car.
The 39-year-old dog walker was approached at about 1600 BST on 14 July in Loanhead Avenue, Grangemouth.
The most recent incident took place on Monday, when a 13-year-old girl reported suspicious behaviour from a man driving a silver car in Stirling Street, Alva, at about 1730 BST.
Insp David Mitchell said: "In all instances the car was grey or silver with four doors. The driver was described as being in his 40s or 50s, with short dark hair, possibly shaved.
"We believe these three instances are linked and we are doing everything we can to trace this person."
He said the dog bite could be quite visible, and appealed for anyone with information about the man to get in touch.
"I also appeal for anyone who may have seen a silver or grey car in these areas around these particular times to come forward," he said.
The incidents are not thought to be linked to the abduction of the 14-year-old girl in Dollar on 21 June.
