Police were called to reports of a fire in the early hours yesterday morning at the property in Kentish Town, Camden, north London, the area that Starmer represents in parliament.

The man was arrested in the early hours of today in connection with the fire and two further incidents, police said.

They are investigating whether a vehicle fire in the same district on May 8 and a fire at the entrance of a property in a nearby area on May 11 are linked to the incident yesterday.

The man, arrested on suspicion of arson with intent to endanger life, remains in custody, police said.

Officers from London’s metropolitan police counter-terrorism command were leading the investigation due to the property’s connections with a high-profile public figure, police said.

Starmer lived in the house on a quiet street with his family before he moved into Number 10 Downing Street when he became prime minister last July.
