Detectives investigating the fatal stabbing of a woman in Gloucester last month are appealing for key witnesses to get in touch to help with their investigation.

Police were called to the junction of Paul Street and Tarrington Road in Tredworth at around 1.45am on Tuesday 27 August with a report that a woman had sustained suspected stab wounds.

Zanele Sibanda, aged 28, was pronounced deceased at the scene.

A man in his 30s and from Gloucester was arrested at the scene and has been charged with murder in connection with the incident.

Officers have now issued CCTV images of four men they would like to speak to who were in the area around the time of the incident.

A fifth man, who officers believe may have witnessed the attack, is described as being white and of a slim build with a bald head. He was wearing a black tracksuit and jacket.

It is believed the five men may have spoken to police as well as other people around the time of the incident.

Detective Chief Inspector Wayne Usher, who is leading the investigation, said: "A man has been charged in connection with the fatal stabbing of Zanele Sibanda, however we are still very keen to identify the five potential witnesses.

"They were in or near Tarrington Road around the time of the incident and we believe they may have crucial information that could help with our investigation.

"I would like to stress that we are not treating these people as suspects. If you are one of the people pictured, I would urge you to contact us so that we can identify you, even if you have already spoken to police and provided your details or information.

"We would also like to hear from anyone who may recognise the men in the images, or who may have seen or heard anything around the time of the incident."

Anyone with information or anyone who knows the men pictured are asked to contact police.

Information can be submitted online and quoting incident 24 of August 27.
