A murderer who escaped from a mental health unit on Wednesday has still not been found.

Police have now released a new image of Lerone Michael Boye in an attempt to trace him.

He is pictured moments before escaping from the John Howard Centre in Kenworthy Road, Homerton, at around 2pm.

In December Boye was sentenced to 28 years in prison for murdering 17-year-old Kelvin Chibueze in Ilford on August 15, 2011.

At the time of his escape he was wearing grey jogging bottoms, a grey and blue sweatshirt and a grey vest over the top.

Police say he is 5ft 10ins tall and slim, with a horseshoe-shaped scar on his right cheek, a goatee and a gold tooth in his upper row of teeth.

Mr Chibueze was stabbed in the Arteflex Club in Ilford High Road.

He was then chased outside and attacked with champagne and brandy bottles before being stabbed again shortly afterwards by two men near Ilford police station.

The public are advised not to approach Boye.
