A student knifed to death outside Harrods was the victim of a robbery that turned fatal, police believe.
A gang of masked robbers attacked Mohammed Abdullah Al Araimi, 20, as he walked near the luxury department store Harrods in Knightsbridge just after midnight on Friday.
The politics and economics student, an Omani national living in London, was pronounced dead at the scene shortly before 12.40am.
A friend told Metro he was stabbed in the back as he tried to fend off the brutal attackers, who are said to have been after his Rolex watch, Metro reports.
A post-mortem examination at Westminster Mortuary gave his cause of death as a stab wound.
His 20-year-old friend was also injured in the attack and taken to hospital for treatment.
He has since been discharged, police said.
A friend of Mohammed told the Mail Online this week: "One of the thieves tried to steal Mohammad’s expensive watch – I think a Rolex – but he fought back.

"There was a struggle and he was stabbed. His friend tried to help and was also stabbed. Mohammad sadly died but his friend survived and is in hospital at the moment.
"This is a truly awful, shocking crime to happen in the middle of London in front of such a famous department store known all around the world."
Detective Chief Inspector Andy Partridge, who is leading the investigation, said: "Mohammed and his friend were returning home from a restaurant when they were approached and assaulted by two male suspects on Basil Street at the junction of Pavilion Road.

"Following the attack, the suspects fled on foot along Basil Street in the direction of Sloane Street.
"I would appeal to anyone who saw two males running along that route, or to drivers who were in Sloane Street around midnight and may have captured any part of this incident on dash-cam footage, to get in contact with my team immediately.
"The victim and his friend were entirely blameless, simply enjoying a meal out together. It does appear that the motive for this cowardly attack was robbery."
