A man has been charged with murdering a commuter by pushing him in front of a Tube train at rush hour.
British Transport Police are appealing for witnesses
The victim, in his 50s, was standing on the platform as a train pulled into Highbury and Islington station, north London, at 1800 BST on Friday.
His relatives are flying in from abroad to formally identify him, said British Transport Police.
A 20-year-old man, arrested in the early hours of Saturday, has been charged with murder.
He will appear at Horseferry Magistrates' Court in central London on Monday.
Police are still looking for people who were on the northbound Victoria Line platform at the time to contact them.
Senior investigating officer Detective Superintendent Ashley Croft said they wanted to trace anyone who was at Highbury and Islington station and who saw the incident.
Chief Superintendent Paul Crowther, of British Transport Police, said one particular witness, aged 20 to 30 and wearing an orange top, appeared to chase the suspect out of the station.
"We know from viewing the CCTV that this was a packed
rush-hour platform and we can tell that a significant number of people saw exactly what happened and were shocked by what they saw."
The Victoria Line, which was shut between Warren Street and Walthamstow following the man's death, is expected to open again as usual on Monday morning.
