A teenage girl’s been sexually assaulted in Hampden Park.
The 17-year-old was leaving the railway station to walk home at around 11.30pm on Valentine’s Day (14 February), when a man rode up behind her on a BMX bike and touched her over her clothing.
He then rode off, but then came back passed her. He is described as a white man in his late teens or early 20s, around 5' 7", and of skinny build. He had stubble on his face and a pointed nose.
He was wearing a black "North Face" jacket with the hood up, black jeans and black shoes. He smelt musty or unwashed. His bicycle was black with a green stripe on the crossbar.
The girl shouted as she was assaulted, and this may have attracted the attention of a man and a woman who had alighted from the same train and who, at the time, were walking some way ahead of her.
The man was thought to be in his mid 30s, wearing a dark jacket and smart shoes, and the woman in her late 20s or early 30s, tall and wearing a pink top.
Detective Constable Costin Bonell, said, "This was a frightening experience for the victim and understandably she was left feeling very upset.
"Anyone who saw or heard anything, especially the two people walking ahead of her, is asked to contact police with information."
They should email email@example.com, quoting serial 639 of 21/02, or they can contact the independent charity Crimestoppers anonymously on 0800 555111.
Details can also be reported online, or they can call Sussex Police on 101.
