Leicestershire Police are asking motorists to check their dashcam footage in case it holds any clues for the murder of 21-year-old Mohammed Jibreel.
Mohammed was found injured in the area of Taylor Road and Kashmir Road, alongside the busy Dysart Way, at around 3pm on Saturday.
He was taken to hospital where he died during the early hours of Sunday morning.
Mohammed was involved in an incident with a group of people in the area of Taylor Road and Kashmir Road between 2.45pm and 3pm before he was stabbed.
Extensive inquiries into the murder continue in the St Matthew’s area and officers have been studying hours of CCTV footage.
Detective Chief Inspector Tony Yarwood, from East Midlands Special Operations Unit (EMSOU), said: “We know from the enquiries we’ve done so far that there were a number of motorists driving along Dysart Way around 3pm.
“Do you have video recording equipment installed in your vehicles, did you capture any footage which may help us? Any information, no matter how small, could help us identify those responsible.”
He added: “Mohammed was a young man whose loss has devastated his family.
“We need to find who did this and we know the local community can help us.
“I want to work with you. We know it’s not always easy to come forward so please been assured that any information you may be able to provide will be treated in the strictest confidence.”
