A newsagent was stabbed to death during a burglary at his shop on Sunday following another weekend of bloodshed in London.

The 54-year-old father-of-one was attacked as he opened the shop in Pinner, north west London, shortly before 6am.

Police and paramedics were called to the scene but he was pronounced dead 45 minutes later. It was the second robbery at the shop within six months.

The senseless murder came barely 36 hours after a 17-year-old was killed in Isleworth, west London, as the knife crime epidemic showed no sign of abating.

Elsewhere in the capital, two teenagers were stabbed in Westminster on Saturday night, a man in his 40s was stabbed in Dalston and a 13-year-old was stabbed in Brixton.

Police said the newsagent’s killer was believed to have stolen the shop’s till and appealed for information from anyone who may have witnessed the incident in the area, part of the capital’s affluent commuter-belt.

The Sri Lankan victim, known locally as Ravi, was well-known in the community and was described as a hard working, popular man.
