A man has denied murdering a student outside the Harrods department store in Knightsbridge.
Badir Rahim Alnazi, 23, is accused of attacking 20-year-old Mohamed Abdullah Al Araimi on 5 December last year.
Mr Al Araimi had been walking with a friend following a meal out when they were set upon.
The King’s College politics and economics student was pronounced dead in the early hours of 6 December.
His brother Salem Abdullah Al Araimi said in a family statement: “Our hearts are eternally broken.”
Mr Alnazi also denied wounding with intent, the attempted robbery of valuables worth £41,610 and possession of a bladed article.
The defendant, of Beaconsfield Road, Brent, north-west London, entered his pleas at the Old Bailey on Friday.
He was remanded in custody and will appear for trial on 6 July.
