A fourth man has been arrested in connection to a series of fires at properties and a car linked to UK PM Keir Starmer.

The 48-year-old man, who hasn't been identified, was arrested at Stansted Airport near London on suspicion of conspiracy to commit arson with intent to endanger life. No one was injured in the fires that occurred between 8 and 12 May at a house owned by Starmer, a building where he once lived, and a car that he had owned.

Three men have already been charged in connection with the fires: Ukrainians Petro Pochynok (34) and Roman Lavrynovych (21), and Ukrainian-born Romanian national Stanislav Carpiuc (26).
