Detectives have launched a murder inquiry after a teenage boy died following the stabbing of a mother and son at a house in north Manchester last night.

Officers were called by colleagues from the North West Ambulance Service to an address on Bednal Avenue, in the Miles Platting area, at about 9.30pm on Thursday, June 9.

A 14-year old boy was treated at the scene by the emergency services for stab wounds before being taken by ambulance to hospital, where he died around an hour later.

His mother - a woman in her 40s - was also treated at the scene for serious stab wounds and was taken to hospital where she is in a stable condition.

Specially-trained officers are supporting the mother and her family at this time.

Initial enquiries suggest the attacker is known to the victims and that this is a domestic incident.

He is described as an Asian man wearing dark clothing, aged in his mid-40s, with a medium build, and a medium height.

He was last seen walking in Sawley Road shortly after the attack took place.

Anyone who thinks they may see him is asked not to approach him and to call 999.

A large cordon remains in place in Miles Platting as investigators continue to probe the scene.

No arrests have been made and a murder investigation is being led by GMP's Major Incident Team.

Detective Chief Inspector Gina Brennand, of GMP's Major Incident Team, said: “Last night’s events are nothing short of devastating as a teenage boy has tragically lost his life and a mother is grieving in hospital after also being seriously attacked.

“We have trained family liaison officers dedicated to supporting her and her family at this incredibly distressing time, and we are committed to doing all we can to make sure we bring the person responsible to justice.

“This is a shocking incident for the people of Manchester to wake up to, but I do wish to stress that our enquiries so far suggest this was a contained and domestic-related incident; however, anyone that sees a man fitting our description looking suspicious should not approach him and call 999.

“This is a ferocious attack that has seen a teenage boy fatally injured and we are working at a tremendous pace to find the person that did this and to take them off the streets and into custody where we can continue to piece together what we know about this utterly tragic incident.”

Anyone with information is asked to call police on 101 quoting incident 3105 of June 9.
