British police arrested a 21-year-old man on May 13, 2025, on suspicion of arson after counter-terrorism officers began investigating three separate fires, one of which occurred at a property previously owned by Prime Minister Keir Starmer. The fire at the property in Kentish Town, Camden, London, was reported in the early hours of May 12, 2025, in the area Mr. Starmer represents in Parliament.

The man was arrested in the early hours of May 13, 2025, in connection with the fire and two other incidents. Police are investigating whether a vehicle fire on May 8, 2025, and a fire at another nearby property on May 11, 2025, are related to the Kentish Town blaze.

The man remains in custody, and officers from the Metropolitan Police Counter Terrorism Command are leading the investigation due to the link to a high-profile public figure. Starmer lived at the property before becoming Prime Minister in July 2024.
