Detectives in Buxton are appealing for witnesses after an 18-year-old woman was robbed as she walked along Leek Road toward the Esso garage.
At around 7.30pm on Friday, January 27, a man came up behind her and pushed her into a wall.
The victim was punched twice to the face and she fell to the floor. She later noticed money had been taken from her pocket.
The offender is described as white, around 5ft 6in tall, of medium build and wearing dark clothing.
Officers would like to speak to anyone who was in the area of the Esso garage at the time and saw a young woman wearing a grey woollen hat.
