Police investigating a grave sexual assault on a woman in Castleford last December are urging witnesses to come forward as their inquiries press on.

Detectives from Wakefield District CID are specifically seeking a woman who interacted with the victim at the Castleford Sports and Social Club before the incident occurred.

The investigation into the incident, which saw a woman subjected to a serious sexual assault in the early hours of Sunday, 16 December on Greaves Street, remains active.

Authorities were alerted at 1.31 am following a report of the incident. A 28-year-old man was apprehended and remains on police bail as investigations continue.

Through meticulous inquiries, police have reason to believe that the victim conversed with a female aged between 20-40 years old before the assault. The woman in question was described as wearing a red skirt, black jacket, and black boots, with long dark hair.

Detective Inspector Sarah Degnan, of Wakefield District CID, said; “We are continuing to investigate this serious incident and the victim has been supported by specially trained officers.

“We know the victim had been in the club on Powell Street before the attack, and that she spoke with another lady there just prior to leaving,

“It is really important we speak with this woman as a potential witness, and I would ask her or anyone else who can assist our enquiries to contact us.

“This lady or anyone else who was in Castleford Sports and Social Club on the evening of the 15 December into the early hours of 16 December can contact West Yorkshire Police via our livechat facility on the website, or by calling 101 and quoting reference 13230692472.
