A teenage killer who stabbed a pupil on a bus to settle "school beef" has been jailed for life at the Old Bailey.

Marvin Dyer, 16 plunged a combat knife through the heart of 15-year-old Baptista Adjei as revenge for jokes he told about him on Snapchat.

He was later caught dancing on CCTV after a friend told him Baptista had died on the phone on October 10.

Dyer boarded the 241 bus in Stratford, East London, wearing a balaclava and a single blue latex glove.

As Baptista came down the stairs, Dyer stabbed the 15-year-old in the heart and lungs, and a second teen was knifed in the arm and knee.

Dyer was only caught because his own mother marched him to Forest Gate Police Station and handed him in when he told her about the attack.

A ban on reporting Dyer's name and publishing his picture had been in place but Judge John Hillen QC lifted the order.

He said: "There is no evidence or no sufficient evidence from which I could determine that lifting anonymity would cause harm to Marvin Dyer, or affect his rehabilitation."

Judge Hillen jailed Dyer for life with a minimum term of 16 years behind bars and told the teen he "left a massive void" in Baptista's family's life.

Judge Hillen said: "You were just six weeks older than him. You have your life, you have taken Baptista’s away leaving what his family described as a massive void in their lives.

"He was a popular boy much loved who showed promise at school and it sports. He and his family had dreams for the future which will never be fulfilled.

"You have not only taken a life but blighted the lives of many others who knew and loved Baptista. You and your victim had fallen out on social media over a bit of inter-school banter."

Hillen also said Dyer already had an "obsession" with knives and had "intended Baptista should die" and there "was a significant degree of planning" involved in the stabbing.

He said: "Already the all too regular spectre of obsession with knives and violence was all too obvious.

"You always intended Baptista should die. There was a significant degree of planning and pre-meditation and there was no immediate provocation and the Snapchat clearly was no justification for any assault."

He went on: "You were armed with a knife and took it to the scene intending to commit murder. I am satisfied you were a mature 15 and now 16 years old. This was your own personal enterprise, not a group attack. I do not consider you to be naïve but calculating."

Baptista’s heartbroken mother, Josephine said: "This senseless killing has taken away his dreams.

"I just cannot stop crying because his killing makes no sense, especially considering Baptista was such a good boy.

"Baptista’s death has left a massive void in our lives we miss and think about him each day."
