A teenage girl has been assaulted in Bristol by a man she says followed her three weeks ago.
The 17-year-old was attacked in Stoke Bishop on Wednesday.
Just after 1600 BST, a man on a bike began following the girl as she walked down Ratcliffe Drive.
He began asking personal questions, before grabbing hold of the girl and knocking her phone to the floor.
She escaped after another man intervened.
The offender is described as a white man in his early 20s, tall and slim, with blonde hair.
He was wearing a blue hooded top, blue joggers and trainers.
Police are appealing for witnesses and information.
