Thousands of mourners bought Kilburn to a standstill as they paid tributes to teenager Quamari Barnes on Friday (March 10).
Sacred Heart Church was filled and others filed into the streets as a horse drawn carriage bought in Quamari's coffin to Bob Marley's music.
Terry Murray who led the service said: "The entire community is in disbelief, the support which you have achieved from the community is tremendous."
Headmaster of Capital City Academy Alex Thomas was also amongst the speakers at the ceremony, which spanned across the day beginning with the funeral at 10.30am.
After the funeral at Old Paddington Green Cemetery, a gathering took place at the school, which was closed for the day.
'The most beautiful, funny service I have ever witnessed'
15-year-old Quamari Barnes was stabbed to death in broad daylight outside Capital City Academy in January and later died in hospital from his injuries.
The news rocked the Brent community and led to a fundraising page for his funeral reaching over £38,300 in less than four weeks.
Tula Heyes who attended the funeral said: "Quamari Barnes, rest in peace, the most beautiful, funny service I have ever witnessed."
Others paid their respects on social media during his "last journey".
Others wrote on Facebook and said: "God rest his soul, we must pray for the Brent community, horrific moment."
A 15-year-old has been charged with murder and will appear for a hearing at Willesden Youth Court on April 25.
