A shop worker has died during a “violent robbery” at a newsagent’s amid a spate of stabbings across the country.
A murder investigation has been launched after police were called to the store in Pinner, northwest London, at about 6am on Sunday.
The victim was found with stab injuries and was pronounced dead 45 minutes later.
A Metropolitan Police spokesman said: “At this early stage it appears the victim was attacked by a man who carried out a robbery at the shop.
“It is thought that the victim worked at the newsagent and was opening the shop at the time of the attack.”
Detective Chief Inspector Simon Stancombe described the incident as a “violent robbery that has escalated” and said police are searching for a till stolen during the raid that may have been discarded.
He also urged anyone who saw a black Vauxhall Astra that was driven away at speed after the attack to come forward.
The victim has not yet been identified, and no one has been arrested in connection with the incident in Marsh Road.
The fatal incident came as the Metropolitan Police confirmed five other people had been stabbed – including a 13-year-old boy – in separate incidents across the capital over 12 hours.
The teenager was taken to hospital after being stabbed in Brixton, south London, shortly before midnight.
The Met Police said his injuries are not thought to be life-threatening.
