14-Year-Old Charged Under Terrorism Act for Alleged Plan to Target London Mosques

The charge specifies section 5 of the Terrorism Act 2006 – preparation of terrorist acts – and alleges conduct in preparation for giving effect to an intention to conduct acts of terrorism, with a time frame stated as on or before 9 July 2026.
Investigators found a number of documents of concern during a search of the address where the boy was arrested, which contributed to the charging decision.
Several outlets describe the case as linked to extreme right-wing ideology, while others label it as extremist terrorism; police emphasise that the core allegation is targeting two mosques in Sutton.
Police say there is no indication of a wider threat but have offered support to the affected mosques and have increased patrols in the area as the investigation proceeds.
The suspect is a 14-year-old who cannot be named for legal reasons; he was arrested on July 9 at a south London address.
A 14-year-old boy has been charged with plotting to attack two mosques in Sutton, south London, under the Terrorism Act 2006, according to BBC and The Independent. Police say the boy, who cannot be named for legal reasons, was arrested on July 9 and has been remanded in custody ahead of an appearance at Westminster Magistrates' Court.
Counter Terrorism Policing London is leading the investigation. Officers say there is no sign of a wider threat, but they have stepped up patrols near the targeted mosques and are offering direct support to both communities affected.
The charge falls under Section 5 of the Terrorism Act 2006. That law covers preparation of terrorist acts — meaning planning or taking steps toward an attack. The alleged conduct is said to have taken place on or before July 9, 2026, The Independent reported. Officials called the charge "highly serious."
The boy also faces a charge of criminal damage to a vehicle, which at least one outlet described as racially aggravated, according to BBC. He is additionally accused of damaging property belonging to another person without lawful excuse. The combination of charges points to alleged real-world action, not just online activity.
When officers arrested the boy at a south London address on July 9, they searched the property. They found a number of documents described as concerning, according to Yahoo News. Those materials played a direct role in the decision to charge him.
Several outlets, including BBC, link the case to extreme right-wing ideology. Police focused their public statements on the core allegation: that the boy was preparing to target two specific mosques in the Sutton area of south London. Investigators have not named the mosques publicly.
Police acknowledged the case would be deeply worrying for local Muslim communities. Officers have increased patrols in the Sutton area. They are also working directly with the two mosques that were allegedly targeted, offering support and security guidance, The Independent reported.
Counter Terrorism Policing London stressed its ongoing links with community groups and partner agencies. Despite the severity of the charge, police said they have found no evidence of a broader network or wider plot connected to the boy.
The boy is due to appear at Westminster Magistrates' Court, though an exact date has not been made public. He remains in custody. Because he is 14, he cannot be named under rules protecting the identities of child defendants in UK law.
The investigation is continuing, according to BBC. Counter Terrorism Policing London has not confirmed whether additional arrests are expected. The case is now one of the youngest terrorism-related charges seen in the UK in recent years.
