Authorities are investigating a series of suspicious fires connected to UK Prime Minister Keir Starmer, including an incident at his £2 million home in North London. A 21-year-old man has been arrested on suspicion of arson following these incidents, which have raised concerns, prompting the involvement of counter-terrorism police. The police are exploring potential links between multiple properties and a vehicle associated with Starmer that were also targeted. Neighbors reported hearing a loud bang before the fire, leading to the area being cordoned off for investigations.
