British police arrested a third man in an investigation into a series of arson attacks in north London, including a fire at a house belonging to Prime Minister Keir Starmer.

The Metropolitan Police force said the suspect was detained on suspicion of arson with intent to endanger life a day after the early-morning fire.

A third man has been arrested in connection with a series of arson attacks linked to Keir Starmer. The 34-year-old was detained this morning in the Chelsea area of south west London. It follows previous arrests related to three separate fire incidents earlier this month.
