A FOURTH man has been arrested in connection with arson attacks on properties linked to Prime Minister Keir Starmer.
The Metropolitan Police said a 48-year-old man had been arrested at Stansted Airport in Essex on Monday on suspicion of conspiracy to commit arson with intent to endanger life.
Police are investigating fires at two properties and a car linked to Starmer.
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.
All three are due to appear at the Old Bailey on Friday.
Lavrynovych, of Sydenham, south-east London, is charged with three counts of arson with intent to endanger life.
Pochynok, of Holloway Road in Islington, north London, and Carpiuc, of Chadwell Heath, east London, are accused of conspiring to commit arson with intent to endanger life.
Two of the fires took place in Kentish Town, north London – one in the early hours of May 12 at the home where Starmer lived before he became Prime Minister and moved into Downing Street.
A car was set alight in the same street four days earlier on May 8.
The other fire took place on May 11 at the front door of a house converted into flats in Islington.
