The teenager denies preparing terrorist acts on worshippers in the area.
Prosecutors say he was arrested for throwing a brick through a car window and a manifesto was later found.
Commander Helen Flanagan, Head of CTP London said: “This is a very serious terrorism charge against a young boy and likely to be highly concerning to the public and the local community. We know this will be particularly concerning to the Muslim community and we are working closely with the venues affected to ensure they are kept updated and to provide advice, support and reassurance, and this will continue.”
Detective Chief Superintendent Nick Blackburn, who is in charge of local policing for the south London area said: “We acknowledge that this will be concerning for the local Muslim community and have been working together with our local partners to provide reassurance and support and I would like to thank all those involved for their understanding.
“We should not underestimate the cumulative impact of incidents of this nature on the Muslim community. These charges come just days after 12 people were arrested for a suspected threat to an Islamic festival in Suffolk and a man was arrested for an alleged assault outside a mosque in Leyton.
“We have been working closely with our colleagues from Counter Terrorism Policing London throughout their investigation and we have increased patrols in the affected areas, which we will look to continue over coming days. As always, should anyone have any concerns, then they can contact us or their local police neighbourhoods team.”
Commander Flanagan added: “While it is deeply concerning to see someone so young charged with offences of this nature, we are sadly seeing an increasing number of children and young people in our casework.
“We continue to work with partners across policing, education, local authorities and safeguarding agencies to help prevent young people becoming involved in extremist ideologies and criminality. However, parents, carers, teachers and others who work with young people also have an important role to play.
“If you’re concerned that a child or young person may be vulnerable to radicalisation, we would urge you to seek support and contact ACT Early. Early intervention can make a significant difference and help prevent individuals from coming to harm or becoming involved in criminal activity.”
