DETECTIVES investigating the fatal stabbing of 16-year-old Rhamero West have made a fresh appeal for information from the public.

Prior to the stabbing on Norton Street, Old Trafford, at around 6pm last Thursday, a series of crashes and violent incidents took place across South Manchester.

Detectives are treating all incidents as linked.

Between 5.30pm and 5.50pm, police received multiple reports of crashes involving a blue BMW and a grey BMW, as well as of armed men fighting one another.

The BMWs crashed several times while travelling along Great Western Street, before turning onto Princess Road.

On Princess Road, the blue BMW swerved in and out of traffic in an attempt to avoid two men, then came to a stop.

One of these men plunged a knife through the driver's window, while the other tried to smash the passenger's window.

The blue BMW then drove off on Moss Lane East in the direction of Upper Chorlton Road, pursued by the grey BMW.

Eventually, after travelling against the traffic, the blue BMW crashed into a tree.

Rhamero and the others in the car fled on foot, with two men from the grey BMW giving chase. The 16-year-old student was stabbed on Norton Street soon afterwards.

Detective Chief Inspector Liz Hopkinson of GMP's Major Incident Team said: "This has been a complex investigation, but our detectives are working at pace as we continue to identify and pursue those we believe to have been involved in these incidents.

"All these incidents occurred in daylight hours on busy roads and we're confident there are people out there who witnessed these events unfold.

"I cannot stress how important it is for those in possession of CCTV footage, dashcam footage or information to get in touch with police as this could prove vital in identifying those responsible.

"We are particularly keen to speak to anyone who has footage of the vehicles or disorder around the Princess Road area and I urge anyone you to get in touch with us as a matter of urgency.

"A family has lost a young son and they rightfully and desperately deserve answers. Do the right thing and come forward."

Anyone with CCTV footage, dashcam footage or other information is asked to submit it on GMP's Major Incident Public Portal.
