POLICE will this weekend be holding an anniversary appeal into a serious sexual assault in Pype Hayes Park.
Twelve months on from the crime, officers will be speaking to visitors to this years firework event to see if they have any information which could lead to the identification of those involved.
The offence took place during bonfire celebrations at Pype Hayes Park at around 8:30pm on Friday November 5 2010.
The victim, a 16 year-old girl, had become separated from her friends when she was approached by a group of four men aged between 16 and 17.
The group offered to help but instead took her to a lake in a separate part of the park and then the toilet area where she was subjected to a serious sexual assault.
As part of the ongoing investigation, officers will be showing visitors to the park an e-fit of a man they want to speak to.
The e-fit is an image of the man police believe is the main offender.
He is described as a white male, aged 16-17 years, around 56 tall, stocky/chubby build, very blue eyes, with tidy eyebrows and a pointy nose.
At the time, he was wearing a purple Adidas hooded tracksuit top and grey Adidas tracksuit bottoms with purple stripes down the side.
Officers are also appealing directly to two of the four men who were present at the time of the incident, but not directly involved, to come forward.
The first is described as white, of chubby build, 16-17 years of age, with short dark hair, freckles on his face, with bushy eyebrows one of which had a slit in it.
The second is described as white, 15-16 years, short dirty blonde hair, blue eyes, and medium build.
