A man with a Zimmer frame made inappropriate, sexual comments to a teenage girl in Chesterfield.
The 16-year-old girl was waiting outside a shop on Saltergate when she was approached by the man, who had a full grey beard and grey hair. The girl walked away.
Officers have since arrested a 47-year-old man in connection with the incident, which occurred last Wednesday at about 5pm. He was released on bail.
Anyone with information or who has witnessed a similar incident in the area should call PC Emma McGovern on 101.
