Man Arrested Over Fire at Starmer’s North London House

A 21-year-old man was arrested on Tuesday in connection with three fires, including one at a north London house that is owned by Britain’s prime minister, Keir Starmer.

London’s Metropolitan Police said in a statement that a 21-year-old man had been arrested in the early hours of Tuesday on suspicion of arson with intent to endanger life. The man remains in custody.

On Monday, counterterrorism police officers took over investigations into the fire. It broke out earlier that day outside the four-bedroom home where Mr. Starmer lived until he won last year’s general election and moved into the prime minister’s official residence, 10 Downing Street.
