Police have arrested a second person as part of an investigation into London’s first murder of 2022 - the fatal stabbing of a man in a busy west London street.
Dariusz Wolosz, 46, was attacked in High Street, Yiewsley, near West Drayton before his killers fled on foot on Tuesday.
It was the suburb’s second murder in five days. Ionut Elvis Tacu, 16, died from a knife wound close to Heather Lane on December 31.
A 27-year-old man was detained on suspicion of Mr Wolosz’s murder on Friday.
A boy aged 13 arrested for the same offence a day earlier has been released on bail to a date in early February.
Mr Wolosz, who was Polish, was attacked near his home by a group of males following a row on Tavistock Road, the Metropolitan Police said.
Officers were called by paramedics to reports of an injured man at 12.12am.
The victim was pronounced dead at 12.43am.
A post-mortem examination gave the cause of death as stab wounds to the groin and chest.
Mr Wolosz’s family are said to be “distraught”.
Police have asked anyone with information to contact them and said dash cam footage from passing cars may have captured the incident.
Detective Chief Inspector Wayne Jolley said: “We believe Dariusz was attacked by a group of males in Tavistock Road following a verbal dispute. The group then fled in different directions.
“The area was busy at the time with passing traffic and people driving past could well have captured dash cam footage of the incident, and the moments leading up to it.
“Dariusz’s family are distraught and we are doing everything we can to support them at this time.
“I urge local people to check any doorbell and dash cameras – you may have captured something that could be very significant for us.”
A 16-year-old, who cannot be named for legal reasons, appeared at the Old Bailey by video-link from youth custody charged with the murder of Ionut - known as Elvis - and spoke only to confirm his identity.
The court was told he was alleged to have taken a knife to the scene and carried out a “planned attack” on an “unsuspecting victim”.
Judge Nigel Lickley QC set a plea hearing for March 24 and remanded the defendant into youth detention accommodation.
Elvis’s death was the 30th recorded teenage homicide in London in 2021, passing the previous peak in 2008 of 29.
It came less than an hour after a 15-year-old boy was pronounced dead following an unrelated stabbing in Croydon, south London.
Anyone who has information on Mr Wolosz’s killing is asked to call 101, quoting reference 0063/04JAN, or Crimestoppers anonymously on 0800 555 111.
