Detectives investigating the stabbing of a 14-year-old boy in south-east London have named two people they want to speak to.
Kellyanne Bokassa died shortly after the attack on the 472 double-decker bus on Woolwich Church Street on January 7.
No arrests have been made but the Metropolitan Police have named 15-year-old Colin Chabekwa and 16-year-old Maswar Zazi as those they are looking for.
Members of the public are urged not to approach any of them if they see them and instead contact police as soon as possible.
Police, paramedics and the London Air Ambulance were called to the scene of the stabbing at 14:30 GMT after an alert was raised by an officer on patrol.
Medics tried to treat Killian’s injuries, but he died soon after.
Det Ch Insp Sarah Lee said Killian’s death had “deeply affected many people in the community”, and thanked people in Woolwich for their support.
“Officers have conducted weapons searches, reassurance patrols and door-to-door enquiries,” he said.
“I know this can be disruptive, however it has been necessary, and your patience is appreciated.”
He added that officers were working “around the clock” to catch those responsible for Killian’s death.
Mary Bokassa, Kellyanne’s mother, told BBC London last week that her son was “very caring” and kind.
However, he said he had experienced some “very difficult times” and had been taken care of for many years.
Ms Bokassa said Killian was raised by gangs from the age of six.
She added: “It hurts because I tried to stop him. I tried so hard, so many times. I screamed at him, I said ‘my son is going to be killed’.”
Killian’s death comes three months after another teenager died in a stabbing in Woolwich.
Dijon Campbell, 15, Stabbed to death on Eglinton Road. on September 22, less than a mile and a half from last Tuesday’s stabbing.
He was among the 11 teenage boys who lost their lives in the 2024 London massacre.
