A 15-year-old teenager has been arrested and detained in connection with the gruesome murder of a young Ghanaian footballer named as Baptista Adjei in the UK.

The suspect was arrested after he handed himself at the East London police station, officials said on Friday.

The Metropolitan Police Department says the yet to be identified suspect remained in custody on suspicion of murder.

Baptista was fatally knifed in his school uniform outside McDonald’s, in Stratford Broadway, at 3:20pm on Thursday.

Online portal metro.co.uk reported that paramedics tried to keep the teenager alive, who witnesses saw collapsed in a pool of blood, but he was pronounced dead at the scene just half an hour later.

Police believe Baptista, who was described by family as a ‘nice boy’, was either attacked while on the bus or shortly after he got off.

His 15-year-old school friend was also rushed to hospital with stab wounds, where he remains with non-life-threatening injuries.

The talented footballer, who was wearing the uniform of Catholic boys’ school St Bonaventure’s, in Forest Gate, when he was attacked, had recently tried out for League One team Ipswich Town.

Baptista, who was described as an affectionate boy who ‘would always make you laugh’, had phoned his mother Josephine to say he was on his way home just 20 minutes before he was fatally knifed.

His mum had offered to pick him up from school due to the delays on the DLR route amid Extinction Rebellion protests.

But he said he would catch the bus after school instead, as he wanted to go to McDonald’s with a friend. His aunt Aretha Adjei said Baptista’s heartbroken mum ‘keeps saying how she should have gone and picked him up’.

She told the Evening Standard: ‘His mother is not coping well. She only has two children. You can’t imagine her pain… ‘He was a fun-loving boy, very popular with everyone in church, everyone in the street knew him.

He would come and put his arms around you. He would always make you laugh. ‘No one could say a bad word about him, he would never join a gang or a group. That’s not him.’

Just five hours after Baptista was knifed, an 18-year-old was found with stab wounds near a children’s nursery in Brandon Estate, Camberwell, south London.

Their deaths take the number of teenagers murdered in the capital this year to 23.

Police have described the attacks as “senseless”.
