The Metropolitan Police said a 16-year-old boy and a 20-year-old woman were arrested at the property and a 20-year-old man was detained nearby. A 43-year-old woman was arrested in Kent shortly after the raid and all four are being held on suspicion of the commission, preparation and instigation of terrorist acts at a south London police station. The injured woman has not been arrested due to her condition, which police described as “serious but stable”. No other injuries have been reported. Police said the property and people connected to it had been “under observation by counter-terrorism officers as part of an ongoing intelligence-led operation”. Further searches at linked addresses across London are under way, although the locations have not been disclosed. The incident has been referred to the Metropolitan Police’s Directorate of Professional Standards and the Independent Police Complaints Commission (IPCC) “as a matter of course”, Scotland Yard said.
