Detectives investigating the escape of a convicted killer from a mental health unit have offered a £10,000 reward for information to find him.
Lerone Boye, 27, was jailed for life in December for stabbing a 17-year-old boy to death at a party in 2011. He received a sentence of 28 years.
He was being held at the John Howard Centre in Homerton, east London, when he absconded on 16 October.
Boye is described as slim, about 5ft 10ins tall with short hair and a goatee beard. He has a distinctive horseshoe shaped scar on his right cheek and a gold tooth in his upper row of teeth.
He was wearing a grey/blue sweatshirt with a grey vest over the top as well as grey jogging bottoms when he was last seen.
Boye attacked and stabbed Kelvin Chibueze at the Arteflex Club in Ilford, east London.
The teenager was chased out of a birthday party and attacked with glass and broken bottles.
A 29-year-old man, Dean Ablakwa, from north London, who worked at the John Howard Centre has been charged with helping Boye escape.
