A young boy, who cannot be named for legal reasons, terrorised his victims from June to November this year.
He mugged a man for his mobile phone after pulling out a three-inch flick knife on him in Dagenham, EsS3x.
The victim asked the muggers to give him his phone back as the boy waved the blade at him, shouting “or what?” before making off with his Oyster card .
UK Mirror reports the out-of-control kid criminal went on to steal sweets from A1 Cash and Carry in Dagenham on October 23 as part of a gang of three.
He returned to the same street on November 11 to rob Londis, where he leapt over the shop counter to snatch cigarettes and alcohol.
The nightmare schoolboy was thrown out by shopkeeper Jedanatha Jeyaseelan.
He was captured on CCTV punching him repeatedly in the head as another boy hit him over the head with a bottle.
The thug admitted three counts of robbery and one of possessing an offensive weapon in a public place.
He muttered “I’m not going to do it again” before receiving a six-month detention order for each count, to run concurrently.
His mum was ordered to pay £100 compensation to be divided between the victims, plus £85 costs and a £30 surcharge.
