British police arrest a 21-year-old man in connection with the fire at Prime Minister Starmer's home.

British police announced Tuesday the arrest of a 21-year-old man on suspicion of arson, after counter-terrorism officers began an investigation into three fires, including one at a property owned by Prime Minister Keir Starmer , Reuters reports.

Police were called to a fire early Monday morning at the property in Kentish Town, Camden, north London, the area Starmer represents in Parliament.

The man was arrested early Tuesday morning in connection with the fire and two other incidents, police said.

An investigation is underway into whether a vehicle fire in the same district on May 8 and a driveway fire in a nearby area on May 11 are related to Monday's incident.

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

Officers from the Metropolitan Police's Counter Terrorism Command were leading the investigation due to the property's links to a high-profile public figure, police said.

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