A 22-year-old man has been stabbed to death in broad daylight in a south-east London residential street.
Police were called at about 12.30pm on Sunday to reports of a man with stab injuries in Samos Road, Anerley.
An air ambulance was also scrambled but despite paramedics' efforts, he was pronounced dead at the scene at 1pm.
Labour MP for Lewisham West and Penge, Ellie Reeves, posted on Twitter that she was "devastated" at the news.
She wrote: "Devastated to hear about the murder on Samos Road today. The second murder in my constituency in 72 hours.
"I am waiting for further details but my thoughts are with the victim and their family. This has to stop."
It comes after 15-year-old Jay Hughes, also known as Jai Sewell, was stabbed to death in Bellingham, south-east London, on Thursday.
The man also died just yards from the park where Michael Jonas Jnr was brutally killed in November last year.
Mr Jonas's father Michael Jonas Sr, 54, today told the Standard he still thinks about what could have happened if he had seen his son on the night of his death. He described seeing his son in a hospital as “the worst moment of [his] life”.
After today's incident he told The Sun: "I can't believe this. There's no end in view.
"I feel so sad, I feel very upset. No one is learning, no one is picking up anything from Michael's incident. People don't really care."
Sunday's murder is the fourth knife death in south London in the space of five days.
