Police in London, England, are hunting Lerone Boye, who was sentenced to life in December for stabbing teenager Kelvin Chibueze to death. Both the convict, who escaped from a mental health centre, and killer are of Nigerian descent.

Reporting on the latest turn of events, The Guardian of London said this afternoon on its website: “Police are appealing for help to find Lerone Boye, 27, who ran away from the John Howard Centre in Homerton, east London, on Wednesday afternoon.

“He was sentenced to life last December for the murder of Kelvin Chibueze and told he must serve a minimum of 28 years.

“His 17-year-old victim was fatally stabbed at the Arteflex Club in Ilford, east London, on 15 August 2011. He was chased out of a birthday party and attacked with glass and broken bottles. Boye’s three co-accused are also serving life sentences.

“Boye is described as black, about 5ft 10in and of slim build with short black hair and a goatee beard. He has a horseshoe-shaped scar on his right cheek.

“He was last seen wearing grey jogging bottoms and a grey or blue sweatshirt with a grey vest over the top. He is known to have links to the Ilford area.

Members of the public have been warned not to approach him but to call 999.

“Anyone with any information about Boye’s whereabouts can also call police on 101 or Crimestoppers anonymously on 0800 555 111.”
