Police have raised the reward for information leading to the arrest of convicted murderer Lerone Boye to £15,000.

The previous reward of £10,000 has been boosted by Crimestoppers, with a further £5,000 now available to anyone who can provide information directly via the phone number below or secure online form.

Lerone Boye, 27, was sentenced in December 2012 to 28 years for the murder of 17-year-old Kelvin Chibueze in Ilford on August 15 2011.

He escaped from the John Howard Centre in Kenworthy Road, Homerton and it is believed he may be in the east London area.

He is also known to have links to Barking, Newham and Ilford.

Boye is described as a black man who is 5ft 10in tall and of slim build. He has a distinctive horseshoe shape scar on his right cheek and a gold tooth in his upper row of teeth.

Tina Chibueze, the mother of murdered Kelvin, recently told the Recorder learning of his escape was a “slap in the face”.

She added: “I’m disappointed in the police for letting him get away, they should have taken him to a maximum security hospital.

“This guy knows my face and is a very dangerous guy. I just want them to get him – we are talking about a murderer.”

When he was last seen Boye was wearing a grey/blue sweatshirt with a grey vest over the top. He was also wearing grey jogging bottoms. He had short hair and a goatee beard.

The public are advised not to approach Boye but to call 999 if seen.

Anyone with any information about Boye’s whereabouts can also call police on 020 8358 0100 or Crimestoppers anonymously on 0800 555 111.
