Kent Police believe that several sexual assaults in the Ashford area were carried out by the same man.
A computer generated image has been made following reports that a 23-year-old woman was assaulted on Friday, August 2.
The victim was walking her dog near Singleton Lake, Kent when the alleged assault occurred.
It is now believed the man responsible could be the same person wanted in connection with two other assaults reported in Ashford last year.
On June 29, 2012, a 17-year-old girl was sexually assaulted as she walked to school.
A 47-year-old woman also reported she had been assaulted on September 6, 2012 as she walked her dog off Britannia Lane.
Police are looking for a white man, around 6ft2ins in his late 30s.
DI Richard Vickery, who is leading the investigation, said: "We are almost certain this man will be known locally and would urge anyone who recognises him or has any information to contact us immediately."
