Kelvin Chibueze murder: Police 'disappointed' at response
Detectives have said they have received "a very disappointing" response to an appeal over the murder of a teenager in east London.
Kelvin Chibueze, 17, from Croydon, died after being stabbed in a disturbance following a party in Ilford.
Officers said no potential witnesses had come forward as they made a fresh appeal for witnesses.
Police were called on Monday at about 04:00 BST to reports of a youth with stab wounds on Ilford's High Road.
He was taken to the Royal London Hospital for surgery but died at about 13:00 BST.
A post-mortem examination gave the cause of death as a stab wound to the chest.
It is believed that two groups, made up of 15 to 20 people in total, were involved in a disturbance following a private party at a premises off Ilford High Road.
The argument spilled out into Ilford High Road and then into the car park next to Lidl and Fitness First, where it is thought the victim was stabbed.
Det Ch Insp John Macdonald said: "We have had a very disappointing response from people who were at the party, no-one has come forward voluntarily to speak to us.
"I would urge everybody who was at the party to contact us so that we can eliminate them from our inquiries."
