Murder Squad cops were today questioning a 17-year-old lad after another teenager was stabbed to death.
Police say the 18-year-old victim was found at a flat in Greenwich, southeast London, on Saturday night following reports of a stabbing.
He was pronounced dead at the scene.
The victim, who has not been named, was the 23rd teenager to be murdered in the capital this year, and the 25th in the last 12 months.
The scene of the latest murder in Prior Street, Greenwich, remains cordoned off.
A Scotland Yard spokesman said: “A murder investigation has been launched after an 18-year-old man was fatally stabbed at a residential address in Greenwich.
“Police were called by paramedics to Topham House, Prior Street, at 9.41pm on Saturday December 8th following reports of a man stabbed and unresponsive.
“Officers attended along with London Air Ambulance. The teenager was pronounced dead at the scene a short while later. His next of kin have been informed. A post-mortem will be held in due course.”
He added: “One male aged, 17, has been arrested in connection with this incident.
“He remains at a south London police station for questioning.
“A crime scene remains in place. Detectives from the Homicide and Major Crime Command are investigating along with police in Greenwich.
“Police are appealing for witnesses and those with information about this attack to contact them.”
A total of 26 teenagers were murdered in London last year, the most since 2008, 20 of whom were fatally stabbed.
