Specialist police have been called in to help in the hunt for a rapist who brutally attacked a young woman in Grimsby six months ago.
The National Crime Agency are now assisting detectives along with specialist criminal profilers following the rape at the Railway Street footbridge which police said left the victim, in her 20s, severely traumatised.
The Senior Investigating Officer leading the investigation, Detective Chief Inspector Stewart Miller, said: “I completely understand the impact offences of this nature can have on a local community, and I want to offer my reassurance today that this is very much an active investigation.
“We have explored numerous lines of enquiry, including reviewing CCTV, speaking to local residents and house to house enquiries, consulting with the National Crime Agency as well as criminal profilers and working with Regional Scientific Support Services to explore all forensic opportunities available to us.
“I have a team of detectives who are dedicated to working on the case, and we are committed in finding the man responsible and bringing him to justice.
A resident who lives on Petchell Way, Grimsby, came to the aid of the woman after hearing "screams of terror" and seeing her being dragged away by a man in a headlock.
Police released CCTV of a suspect walking towards Victor Street from Oxford Street in the East Marsh.
DCI Miller said earlier in the investigation: “We are asking anyone that recognises him to call in as we believe he may have information that could assist our enquiries."
He added: "Detectives investigating the report are following up a number of lines of enquiry which includes looking at CCTV from the area to identify anyone that may be able to help."
Police arrested three people following the attack, all of whom have been released , and are still hunting their main suspect who was caught several times on CCTV.
The rape victim had left work around midnight and was followed along Freeman Street into Wellington Street and on to Railway Street before her horrific ordeal.
Just as she was about to go over the footbridge she was dragged to a secluded area of ground and brutally raped by the man, who was not known to her.
DCI Miller added: “Support for the victim is being maintained through our specialist officers and we always ensure she is kept up to date with the investigation and the action that we are taking.
