Residents have not been allowed to return to Heron House, where the youth was shot dead Three people are being questioned by police after a teenager was shot dead and two youths were stabbed on a south London housing estate.
Police found a 17-year-old who had been shot dead in a stairwell at Heron House on the Pelican Estate in Peckham, at about 1630 GMT on Wednesday.
Officers also found a 17-year-old with a stab wound at Gannet House. Police suspect the incidents are linked.
Those arrested are male, but their ages are not known.
The stab victim was taken to a south London hospital where he is in a stable condition.
Police were later alerted to a third victim, an 18-year-old man, after he arrived at a south London hospital, also suffering from a stab wound.
He was later discharged with minor injuries.
“Officers are treating all three incidents as linked at this early stage,” a Metropolitan Police spokesman said.
Forensic officers have been investigating the scene A large police cordon has been put in place around the estate and officers have not let residents back into Heron House, where the victim died.
Residents who lived close to the site of the shooting said they heard a large bang coming from Heron House.
“I thought someone was setting off an early New Year’s Eve firework,” said one woman.
But a man who lived nearby said he knew instantly it was a gunshot.
“I heard a loud bang,” the 43-year-old said.
“I have never heard a sound like it before, but I knew it was a gunshot.”
He later came across the crime scene as he tried to leave the block of flats.
“I live on the fifth floor and I went out to the lift.
“Then I saw a lot of blood outside the lift on the floor. The police were already there,” the man said.
