Police today offered a £20,000 reward as they try to trace two men after a student was stabbed to death when masked muggers targeted him for his Rolex watch.

Mohammed bin Abdullah Al Araimi, 24, was murdered on December 5, 2019 after being set upon as he strolled home from a restaurant in London outside Harrods.

The Omani national was stabbed in the back at about 1am after trying to resist his attackers outside the department store in affluent Knightsbridge.

Scotland Yard detectives have released CCTV footage of two men they want to identify who were seen walking together in London's Knightsbridge in the early hours of December 6

Today, Scotland Yard offered a reward of up to £20,000 for information leading to the identification, arrest and prosecution of the people responsible for the attack.

Detectives also released CCTV footage of two men they want to identify who were seen walking together in Knightsbridge in the early hours of December 6.

King's College student Mr Al Araimi was stabbed along with his friend, a 20-year-old man who was taken to hospital for treatment but has since been discharged.

Mr Al Araimi, who was said to have lived in the UK for three years, was found unconscious after the attack at 11.55pm, and pronounced dead at 0.39am.

A friend of the victim told MailOnline last month: 'Mohammed was walking past Harrods with a friend from Bahrain when they were confronted by muggers.

'One of the thieves tried to steal Mohammed'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. This is a truly awful, shocking crime to happen in the middle of London in front of such a famous department store.'

He had been out for a meal with a friend at a restaurant on Pavilion Road, before leaving and walking along Basil Street, heading towards Sloane Street.

Detective Chief Inspector Andy Partridge said: 'The attack on Mohammed and his friend was a planned robbery that was truly shocking and extremely violent.

'I am convinced that the public can provide names for those males featured in the CCTV images we have released today. My team have secured hundreds of hours of CCTV footage.

'The suspects involved in the attack travelled on foot from the Edgware Road / Marble Arch area of London to Knightsbridge prior to carrying out the attack.

'This location is therefore potentially very significant, with the persons we are seeking to identify having a connection to this area.

'There is a substantial reward being offered in this case and I ask that anyone who knows the identity of the two males makes contact with my team. All calls will be treated in the strictest confidence.'

A post-mortem examination took place at Westminster Mortuary on December 6 and gave the cause of death as a stab wound. There have been no arrests.

Police said anyone who might know who the two men are or has information that may assist detectives should contact the incident room on 020 8358 0300.
