A 44-year-old man has been arrested in Kent on suspicion of murder after a teenager was stabbed and his mother was injured in a Manchester home, Greater Manchester police said.
Police said the man, from Manchester, was believed to be known to the victims. Officers were called by colleagues from the Northwest Ambulance Service around 9:30 p.m. Thursday after the domestic incident at Miles Platting.
The 15-year-old boy was treated at the scene for stab wounds before being taken to hospital where he died about an hour later, the force said.
Police say her 40-year-old mother was treated at the scene for serious stab wounds and is now in stable condition at the hospital.
DCI Alicia Smith said: “Last night’s attack has left a community faltering and a family that has come to terms with what was an absolutely devastating incident for all involved.
“A teenager who had his whole life ahead of him has tragically lost his life and his mother is not only mourning the loss of her son, but also recovering from what would no doubt have been very traumatic.
“Our thoughts remain with the family and we are absolutely committed to establishing what exactly happened last night.
“Detectives have been working all day since they first informed us of this incident and we have now made an arrest, which is a big step forward in getting the family the answers they need.
“Our inquiries are ongoing and we would still like to hear from anyone with information or anyone who has seen anything. Please report it online or via LiveChat at www.gmp.police.uk or alternatively contact us. with Crimestoppers anonymously on 0800 555 111.
