The incident took place around 7.20pm on Monday July 16, when a 15-year-old’s was grabbed by a man as she was walking along the footpath between Dunbar Court and the Leslie viaduct.
She was able to free herself and run away, but police have so far been unable to identify the culprit or his motives.
Police described the incident as “frightening and unprovoked”.
The man is described as white, aged between 18 and 40, 5ft 11in tall, of slim build with stubble. He spoke with a local accent in a deep voice.
He was wearing a black hooded zip-up top with the hood up, black tracksuit bottoms and black trainers with white soles.
Detective Inspector Paul Dick, of Kirkcaldy CID, said: “High visibility patrols were conducted in the area one week on from the incident and a number of people have been spoken to as part of this, including three males seen using a motorbike in the area at the time who we previously appealed for.”
