A girl was approached by an elderly man in Biddenham on Wednesday (March 2) who touched her and made lewd, sexual remarks.
The girl was walking with a group of friends along Oldfield Road at around 3.30pm when the incident happened.
The girl ran away from the man who then left the scene.
The man is described as elderly, Asian, and dressed all in white.
Detective Sergeant Katherine Rivers, investigating, said: “This was naturally a distressing incident for the girl and no-one should have to put up with hearing inappropriate comments like this.
“I’d like to reassure the community that fortunately the girl was not physically assaulted nor hurt during the incident, and we are working hard to find the person responsible for what we believe to be an isolated incident”
Anyone who has any information about the incident is asked to contact DS Rivers on 101 or call Crimestoppers, anonymously, on 0800 555 111.
