A police van arrived at Westminster Magistrates' Court on Thursday, 2 May, where Marcus Aurelio Arduini Monzo is appearing charged with the murder of 14-year-old Daniel Anjorin in Hainault.
The teenager died on Tuesday as he walked to school.
The 36-year-old dual Spanish-Brazilian national, of Newham, will appear in court having been charged with murder, two counts of attempted murder, two counts of grievous bodily harm, aggravated burglary, and possession of a bladed article, the Metropolitan Police said.
Monzo is accused of crashing a van into a fence and then attacking two members of the public with a sword.
It is alleged he then killed Daniel before seriously injuring two police officers.
