A 15-year-old boy has been charged after a man in his 30s was stabbed to death on a residential street in Sydney's inner west.
Officers attended an address in Concord at 12.30am on Saturday following reports of a stabbing.
They arrived to find a man with stab wounds to his chest lying in the driveway.
The man, who is yet to be formally identified, was treated by paramedics and received CPR but died at the scene.
Police seized a weapon they allege was used to kill the man, saying it was "more than a kitchen knife".
"Today, one life was lost and one life will be ruined," Superintendent Christine McDonald told reporters.
"It is why we have laws against young people carrying knives on our streets.
"One day, in the spur of the moment, you may use that knife; you may kill someone with that knife.
"And if that day comes, you will likely be facing a murder charge and jail time."
Following inquiries, detectives arrested the 15-year-old boy after he was found nearby.
He was taken to Burwood Police Station and charged with murder.
The boy was refused bail to appear before a children’s court on Sunday.
