A 28-year-old man, who had been in critical condition since Thursday, is now in custody after the suspect was arrested on Friday.

According to British Transport Police (BTP), a man passed away following what is believed to have been an assault at a London Tube station.

The victim, who is presently only known to be a 28-year-old man, passed away on Saturday night in the hospital, surrounded by his loved ones, after being in serious condition since Thursday.

According to BTP, on Thursday at 9:44 p.m., police were dispatched to Southwark station in southeast London in response to allegations of an attack on the staircase.

The following morning, Southwark resident Rakeem Miles, 23, was taken into custody and accused with intentionally causing great bodily harm.

According to BTP, he is in custody.

Detectives are now seeking to update the charge to reflect the change in the victim’s condition.

Senior investigating officer DI Paul Attwell said: “There is no place for violence on the rail network and I am urging anyone with information, who is yet to speak to us, to get in touch.

“We have specialist family liaison officers supporting the victim’s family and my thoughts remain with them at this incredibly difficult time.”
