Farmanullah Sherzad, 26, collapsed in Abbey Orchard Street on Friday evening.
The Metropolitan Police were called to reports of a stabbing in Westminster at 10.17pm.
Officers arrived within minutes and found a man suffering from stab wounds.
Despite the efforts of officers and paramedics, the victim was later pronounced dead in hospital.
Mr Sherzad’s killing happened just a few minutes’ walk from the abbey and St James’s Park.
Two men - aged 18 and 21 – arrested on suspicion of murder remain in custody.
He died at the scene in Chalton Street despite the efforts of paramedics to save his life.

“To provide reassurance, officers will be carrying out extra patrols in the area over the coming days and will be available to speak with anyone who has concerns.”
