A 21-year-old man was arrested on suspicion of arson in connection with three suspicious fires, including one at the former home of UK Prime Minister Keir Starmer in north London. The Metropolitan Police, with assistance from counterterrorism officers, are investigating the incidents, which also include a car fire and another fire at an apartment door linked to Starmer. No injuries were reported, but there was damage to the entrance of Starmer’s family home, which is currently rented out; inquiries into the cause of the fires are ongoing.
