A murder investigation is under way after a shop worker was stabbed to death during a robbery at a newsagent's in north-west London, police said.
The man is believed to have been attacked as he opened Marsh Food and Wine in Pinner, on Sunday morning.
The victim was pronounced dead at the scene and police said enquiries were under way to identify the man and his next of kin.
It comes amid another night of bloodshed in the capital with six more people stabbed as the number of homicides in London reaches 29 this year.
