A man has been arrested in connection with fires at properties linked to UK Prime Minister Keir Starmer in London.
The 21-year-old was arrested early on Tuesday on suspicion of arson with intent to endanger life. He is in custody.
The arrest relates to three fires, including at a Kentish Town property where the Prime Minister used to live. Mr Starmer is understood to own the home.
The man is also being questioned over a vehicle fire in the same street and a fire at the front door of a house converted into flats in nearby Islington, which is also linked to Mr Starmer.
The Metropolitan Police said in a statement that they were alerted by the London Fire Brigade at 1.35am on Monday to reports of a fire at residential address in north London, where damage was caused to the property's entrance. Nobody was hurt.
“As a precaution and due to the property having previous connections with a high-profile public figure, officers from the Met’s Counter Terrorism Command are leading the investigation into this fire. Inquiries are ongoing to establish what caused it," the statement said.
Police are also investigating whether the vehicle fire on Thursday and the fire at the entrance of a property on Sunday are connected to the fire at Mr Starmer's former home.
“All three fires are being treated as suspicious at this time and inquiries remain ongoing,” police said.

After becoming Prime Minister, Mr Starmer moved to the official residence at 10 Downing Street.
“I can only say that the Prime Minister thanks the emergency services for their work and it is subject to a live investigation," his official spokesman said. "So I can’t comment any further.”
In June last year, three pro-Palestine protesters demonstrated outside Mr Starmer’s former home. They were not jailed.
