Extra police patrols are taking place around Brent schools after 15-year-old Quamari Barnes was stabbed to death in broad daylight outside Capital City Academy last month.
Officers from the Queen's Park ward said they were asked to "patrol more outside schools in response to the death of a pupil".
In a police ward panel meeting on Wednesday (February 15), officers added: "Police have also been visiting schools to speak to students about crime awareness."
Vice Principal of Capital City Academy, Ms Marianne Jeanes, told getwestlondon: "We're aware of the new patrols happening around the schools.
"We're grateful for the extra support police have given us."
The decision by the Metropolitan Police comes after the tragic death of Quamari Barnes , which officers confirmed was not gang related.
Officers found him suffering from stab injuries and he was taken to a central London hospital where he died.
A post-mortem examination gave the cause of death as a haemorrhage and a stab wound to the chest.
A fundraising page was created to raise money for his funeral costs, which raised almost £15,000 and saw friends and family pay tributes.
Speaking after his death, Quamari's sister, Pierao Serunkuma-Hutton, said: "Quamari was a much loved boy with a heart full of gold.
"Everyone who knew my brother loved him to bits.
"He was such a good role model to everyone, old and young."
A 15-year-old has been charged with murder and appeared at Willesden Youth Court on January 27.
