An appeal for witnesses has been renewed following a sexual assault earlier this year.
A CCTV image has been released of a man who is believed to have been in the area of the attack that happened inside an address on Pechell Street on January 30.
The man is described as being Asian, large build, aged in his 30s or 40s with balding hair and slight stubble.
He was wearing a blue top, dark trousers and brown shoes.
DC Melanie Caunce said; “We have released an image of a man that we believe was in the area at the time of the offence and we are appealing for him or anyone who recognises him to come forward.
“If anyone has any other information that they think could help, I would ask them to contact us.”
There is a possibility that the offender may be from the Blackburn area.
