Detectives in Lancashire are trying to identify a man who fell from a railway bridge in Colne.
Paramedics were called to the scene on the town's Knotts Lane last Sunday evening, but could not save him from his injuries.
Officers have released an artist's impression of the man, who was believed to be aged between 40 and 55.
He was around 5ft 9in tall. He wore glasses, blue trousers, a blue and white checked shirt, a grey jumper, and a brown zip-up jacket.
The man carried no ID of any kind.
Detective Inspector Jez Holland said: "While he doesn’t match any of our missing person’s records, he is someone’s father, brother or uncle and surely someone, somewhere is missing him and wondering what has happened to him."
Police are appealing for witnesses a 35 year old woman was raped on her way home from a night out in Colne on Saturday.
The attack happened sometime between 9.40pm and 10.15pm at the rear of Exchange Street and Blascomy Way when the woman has encountered a lone man smoking a cigarette.
It is believed the man may have been disturbed during the attack when someone has been heard speaking further up the backstreet.
This appears to be an opportunist attack on a vulnerable lone woman returning home from a night out.
“This is a vicious crime which has had a significant impact on the victim who is being supported by specially trained officers”.
“I would appeal to anybody that saw a man acting suspiciously in the area around the time of the offence or anyone that thinks they may have witnessed this incident to contact police as a matter of urgency.”
– Detective Inspector Jim Elston
Officers are carrying out CCTV and house to house enquires but anyone with any information that could assist police with their investigation should contact Lancashire Police on 101.
A 35 year old man from Colne has been arrested on suspicion of rape and is currently being questioned by officers.
