A teenage boy murdered in Ilford died as the result of a stab wound to the chest.

The post-mortem for 17-year-old Kelvin Chibueze was carried out in East Ham yesterday.

He was attacked at 4am on Monday after two groups containing 15 to 20 people in total faced-off against each other just yards from Ilford Police Station.

The youngster had been among a group celebrating a friend’s birthday at a premises off High Road when an argument spilled out on to the street.

Police found him lying injured in a car park off Thompson Close.

He died nine hours later in the Royal London Hospital, Whitechapel.

Det Ch Insp John Macdonald, leading the murder investigation, told the Recorder knives and other weapons were found at the scene, and the attack was not random.

It is not known at this stage if the weapons found are linked with the murder.

He added: “You’d expect a number of people would have come forward but no one has.

“People disappeared straight away. It underlines some of the difficulties we’re facing.”

He said as many as 30 people may have key information about the murder and the events leading up to it.

Anyone with information is asked to call the incident room on 020 8345 3985 or call Crimestoppers anonymously on 0800 555 111.

• A 19-year-old man arrested on suspicion of murder on Monday has been bailed until late September pending further inquiries.
