British police say they have arrested a man on suspicion of arson with intent to endanger life over a fire at the London house where Prime Minister Keir Starmer lived before he was elected to lead the country.

The 21-year-old was arrested early Tuesday.

No one was injured in the blaze early Monday that damaged the door of the north London house.

Starmer does not currently live there. Since taking office in July, Starmer has lived with his family in the prime minister's official Downing Street residence.
