Teen stabbing: Police release CCTV
Detectives have released the picture of a 15-year-old boy they want to question over the suspected murder of a teenager.
The CCTV image, filmed on a bus on Sunday, is believed to be the last sighting of Dawda Jallow, from the Peckham area of south-east London.
Police want to speak to Jallow in connection with the fatal stabbing of Dogan Ismail, 17, also from Peckham.
Dogan was killed on the Aylesbury Estate in nearby Walworth on Sunday after going there with his 15-year-old brother, Orhan Ismail.
Officers confirmed that the brothers had gone to the notorious estate to recover a BlackBerry phone stolen from Orhan on Friday.
There they encountered a group of four males and during an "altercation" the victim was fatally injured.
Det Chief Insp Matt Bonner, of the Homicide and Serious Crime Command, leading the investigation, said: "It would appear that on the Sunday they went back on to the estate in an effort to recover that phone."
In a statement released through police, Dogan's family said: "Our beloved son, friend, cousin, nephew and grandson has been cruelly taken away from us. Words cannot describe how much we will miss him. We want justice for Dogan and his killer caught. Anyone with information, please tell the police."
On Monday, officers took the highly unusual step of naming Jallow as they appealed for help in finding him. The image shows him travelling on the number 35 bus between Camberwell Green and Newington Causeway just after 10.30pm on Sunday.
"If anyone knows him, if anyone knows where he has been staying, if anyone has any ideas that they should put him up for the night, I would urge them not to and call us instead," DCI Bonner said. "He must be staying somewhere and so I am urging the community for their help in letting me know where that is."
