Two teenagers have been charged in connection with the first knife attack on a boy stabbed twice in four days. 

The two 15-year-old's from Chingford and Walthamstow were arrested yesterday (June 9) and charged with greivous bodily harm (GBH) after a 16-year-old boy was stabbed in Hall Lane, Chingford, on Thursday. 

Police launched an appeal for information after there was no sign of the teenager or any suspects at the scene. 

The teenager admitted himself to hospital later that day with a stab wound to his upper chest and arm. 

The pair were remanded in custody to appear at Stratford Magistrates Court today alongside a 17-year-old charged with GBH in Withy Mead on Monday.  

Just 48 hours after being discharged from hospital on Saturday, the same 16-year-old was stabbed a further three times in both his legs and shoulder in Withy Mead, Chingford, at around 6.30pm. 

His mother told the Guardian yesterday her son is recovering from five stab wounds, four of which are on the left side of his body. 

A 21-year-old arrested in connection with the Withy Mead stabbing has been bailed to a date in July.

Detective Chief Inspector Mike West, of Waltham Forest CID, moved to reassure the public about violent knife crime. 

He said: "Tackling youth violence and knife crime is a priority for us here at Waltham Forest.

"We work closely with our partners to carry out a wide range of operational activity to reduce crime, incorporating crime prevention and engagement tactics wherever there is an opportunity to do so.

"We also continue to use our colleagues in schools and the youth sector to target locations where these crimes are occurring, in our constant drive to make Waltham Forest the safest place to live and work." 

Detective Inspector Shaun Fitzgerald, of the Trident Gang Command, said overall knife crime in London is 30 per cent lower than before the launch of its gang unit in 2012. 

He added: "Those who commit crime and bring violence to the streets of London should be aware that we will do everything possible to arrest and place you before the courts.

"We also support Government proposals for tougher sentencing of offenders."
