Police have contacted the victim linked to the damaged vehicle.The terrorism charge relates to an alleged plan to target two mosques in the Sutton area, which are both being supported by specialist officers, police said.The boy has been remanded in custody to appear at Westminster Magistrates' Court on Thursday.The Met Police say they do not believe there is any wider threat in relation to the incident and are not seeking any other people in connection with their investigation.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."DCS Blackburn said there will be increased patrols in the affected areas, which will be monitored over coming days.Commander Flanagan said police are seeing an increasing number of children and young people in their casework."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," she said.Article continues below"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.
