According to Evening Standard UK, Orebiyi was stabbed in a street clash close to Westbourne Grove just yards from the Portobello Arts Club.
The 17-year-old was reportedly involved in a fight on a nearby estate with a gang of youths, who chased him into the busy road where he was attacked.
Police and paramedics tried to resuscitate him for a long time but to no avail. He collapsed and bled to death.
The deceased’s neighbor, Osman Sahal, told the police: “He was a nice boy and very considerate none of us can understand how this could have happened.
“As far as I knew, he was never in trouble I suppose we must now wait for the police to investigate.”
Orebiyi, who completed his General Certificate of Secondary Education, GCSE, at Holland Park in London was studying for his A levels at the Chelsea Academy before his death.
