E-Fit After Aylesbury Rape
Thames Valley Police have given Heart this image of a man they want to speak to after a teenage girl was subjected to a serious sexual assault in Aylesbury.
The 19-year-old was attacked near to Aylesbury train station between 1.30am and 2am on Friday 17 February.
The man in the image is described as being of mixed race origin, around 20-years-old, 6ft with a broad build.
He has distinctive bright green eyes. He was wearing a dark blue cardigan that had white thick striped details and a hood, a white cotton high neck top and dark blue jeans.

"I am keen to hear from anyone who recognises the man in this image.
"We continue to take this matter very seriously and have a number of dedicated officers working on this case.
"Anyone who has any information that could help us progress this investigation should contact me urgently."
