Detectives investigating the fatal stabbing of a man in London have arrested a teenager on suspicion of murder.
Metropolitan Police said a 13-year-old boy was arrested on Thursday. He remains in police custody.
Officers were called to report an incident on High Street, Yiewsley, West Drayton around 12:12 am Tuesday.
Officers attended the scene and the injured man was treated by paramedics but was pronounced dead at around 12:43 am.
The victim was later named Dariusz Wolosz, who lived in the area.
An autopsy performed on Thursday gave the cause of death as stab wounds in the groin and chest.
Chief Detective Inspector Wayne Jolley, a crime specialist, is leading the investigation.
He said: “We believe Dariusz was attacked by a group of men in Tavistock Road following a verbal argument. The group then fled in different directions.
“The area was busy at the time with traffic and those walking past could very well have captured dash camera footage of the incident and the moments leading up to it.
“Dariusz’s family is distraught and we are doing everything we can to support them at this time.
“I urge the locals to check the doorbells and dash cams to verify them; you may have captured something that could be very important to us.”
