Four thugs took a child along to launch a “wicked and disgraceful” ambush on a rival gang member in broad daylight, which left their stabbed victim bleeding on a shop floor.

Jerome Odigie, 22, was knifed twice in front of horrified staff in a convenience store in Goldsmith’s Row, Haggerston.

Andrew Odukoya, 22, Ikem Affia, 24, Michael Omoshola, 23, Cleon Brown, 22, and a 15-year-old boy, who cannot be named, hunted their victim in two separate cars before spotting him outside the shop.

The onslaught was over within the space of a minute leaving Mr Odigie with a torn peritoneum and another gash to his chest, after Odukoya delivered two swift stab wounds in rapid succession.

Judge Sheelagh Canavan said they were lucky they had not killed Mr Odigie during the attack on January 14 this year.

“You chose to commit a group attack to satisfy your own personal grudge, whatever that may be,” she said.

“Crimes such as these committed in front of the public have a profound effect on us all.

“You are all young men with real potential, which you have done nothing but waste.”

Judge Canavan said of the four older defendants: “They were prepared to commit this crime and take a child along with them to commit it. Adults have a responsibility to children – not the other way around.”

Odukoya was convicted of wounding with intent following a trial last month and his four co-defendants were convicted of the lesser offence of unlawful wounding, based on the jury finding they had no prior knowledge of the weapon but were part of the ‘joint enterprise’.

Mr Odigie refused to testify against his attackers at their trial last month.

Odukoya, of Brodia Road, Stoke Newington, had been convicted for violent disorder following the London riots in 2012.

He was sentenced to 10 years in prison, extended for two years, at Snaresbrook Crown Court last Friday, and will not be released until he is no longer deemed a risk to the public.

Affia, of Woolridge Way, South Hackney, who was found in possession of a knife and a gun in 2008 and 2009, was handed a 30 month sentence with a consecutive six month term as this offence was committed in breach of a previous suspended sentence.

Omoshola, of Ainsworth Road, South Hackney, who was convicted of hitting someone over the head with a fire extinguisher in 2013, received a 30 month sentence, as did Brown, of King Edwards Road, South Hackney.

Brown had been convicted of two counts of rape in 2008.

The 15-year old was handed an 18-month youth rehabilitation requirement with 18-months supervision and four month curfew. He must also attend a weapons awareness programme for 10 days, and was given two prohibited activity requirements.
