Teenage Girl Attacked And Robbed At Wimborne Bus Stop
Police are investigating an attack and robbery on a 16-year-old girl in the Merley area of Wimborne.
It happened at around 11.10am on Friday 7 November 2014 at the bus stop opposite Merley First School in Oakley Straight.
A 16-year-old girl from Wimborne was standing at the bus stop looking at the timetable with her headphones hanging out of her pocket when she was pushed from behind causing her to fall into the bus shelter.
As the victim tried to get up she was pushed again causing her to hit her head on a wooden bench inside the shelter.
When she got to her feet she saw a man running away toward Wimborne with her red and pink headphones in his right hand.
The victim was left with bruises to her face and body.
The offender is described as white, five feet six inches tall and of muscly build. He was wearing dark coloured jeans, a leather jacket, a dark coloured hooded top with the hood up and padded ski gloves.
Police Constable Julie Payne, of Poole police, said:
"This was a frightening attack on a teenage girl in broad daylight and fortunately she did not suffer more serious injuries.
"I am keen to speak to anyone who may have seen this incident or has any information that can assist with the investigation. I urge witnesses and anyone with information to come forward as soon as possible.
"All calls are treated with the strictest confidence."
There have been no arrests.
