COPS investigating a rape in Glasgow have appealed to three men who were in the area at the time of the assault and may have seen something.
The 27-year-old victim was targeted by the rapist more than a month ago and cops now believe these three men may have seen something which will help them catch the man responsible. 
The woman was walking on a path between Byres Road and Glenmalloch Place in Elderslie, when she was approached by a man who struck her, causing her to fall from the ground. 
He then subjected her to a serious sexual assault at around 8pm on Monday, February 20.
The suspect is described as white, between 35 and 50 years of age, of medium to stocky build with dark hair that is receding on top. He was wearing dark coloured trousers and a light coloured t-shirt.
Detective Inspector Louise Harvie said: “Extensive enquiries are continuing to trace whoever is responsible for this serious sexual assault.
“There are three men that officers wish to trace as they were seen in the area near to where the incident took place, and may have seen the suspect or unwittingly witnesses something vital to this investigation.  I would urge them to come forward and speak to police.
“The first man was seen in Stoddard Square, Elderslie around 8pm on Sunday or Monday, February 19 or 20.  He is described as between 30-50 years of age and wearing dark trousers and a light top.
“The second man was seen near to the Wallace Monument in Main Road, Elderslie around 8.15pm on Monday, February 20.  He is described as in his 30s, 5ft 10 ins in height and of stocky build with short dark hair and clean shaven.  He was wearing dark coloured trousers and a dark coloured parka-style jacket.
“The third man was seen near to the Wallace Monument in Main Road, Elderslie around 1.10am on Tuesday, February 21.  He is described as 30 to 40 years of age, broad build and wearing dark coloured jeans, black jacket and white trainers."
