The Metropolitan police is hunting for a killer after a 43-year-old man was stabbed to death in west London.
Naython Muir died after being stabbed in Parkside Road, Hounslow, on Friday night.
Police officers and the London Ambulance Service rushed to the scene but he could not be saved.
The police force said the man’s next of kin have been informed and a formal identification awaits.
The Met added that there have been no arrests and a post-mortem examination will be scheduled in due course.
A crime scene remains in place, reported The Mirror.
Detective Chief Inspector Brian Howie from the Met’s specialist crime command, who is leading the investigation, said: “We are in the very early stage of our investigation and my team of experienced detectives are working diligently to find out who is responsible and to establish the full circumstances of Naython’s murder and why he was attacked.
“I am appealing to anyone who was in the area and witnessed this incident, or the events leading up to it, to get in contact.
“I am particularly keen to speak to people who were in the vicinity of Parkside Road, Argyle Road and St Stephen’s Road between 10pm and 11pm – you may have seen or heard something that could assist us.”
He added: “I would also ask residents to check CCTV, dash cam and doorbell cameras to see if they have captured anything of interest.
“We have set up a dedicated web portal where material can be uploaded.
“Someone must know why Nathyon, also known as ‘Nayff’, was attacked – his family are devastated and are desperate for answers. If you can help, then please get in touch.
“A crime scene remains in place and I thank the community for their patience while this vital work is carried out.”
