Newham Detectives are making a fresh appeal for information to solve the murder of a teenager in East Ham a year ago.

St Bonaventure’s student Ailton Campos De Oliveira died at the Royal London Hospital in Whitechapel on July 6. He was found with stab injuries just after 1am on Sunday July 4 in Denbigh Road, East Ham.

Ailton, 16, was pulled from his distinctive bicycle by a group of teenagers in Boundary Lane, Plaistow. They pulled him from the bike, stealing it, before then chasing him into Denbigh Road where he was fatally wounded.

A post-mortem examination gave cause of death as a stab wound to the chest.

There is a reward of up to �20,000 for information leading to the identification, arrest and prosecution of those responsible for the murder.

Detective Inspector Tony Lynes, who is leading the investigation, told the Recorder that at this stage they are not looking for witnesses. Rather, he said: “We know there are people in the community who know what happened and who is responsible. It is an appeal to the hearts and the consciences of those people. We need them to come forward.”

He urged anyone with information to consider Ailton’s distraught family. In the days after his death his family appealed for calm and help to catch his killers.

Det Insp Lynes admitted that a year on they are no closer to establishing a motive for the brutal attack on Ailton. He believes there are people in the Plaistow, Maryland and Stratford areas who know those directly responsible for the attack.

Officers also want to trace Ailton’s bike which is a black ‘Hardrock’ model, with the brand ‘Specialized’ in red letters along the body. It features distinctive customised white front shock absorbers, which had been fitted by Ailton.

Along with his bike, the suspects also stole Ailton’s Blackberry ‘Curve’ mobile phone.

An incident room has opened at Barking under Detective Chief Inspector Charlie King, Homicide and Serious Crime Command.

Anyone with information is asked to call the incident room on (020) 8345 4142.
