Police have been given more time to question a second man arrested in connection with the trio of fires linked to the Prime Minister - after nabbing the suspect at the airport.
Sir Keir Starmer's home, as well as a flat and a car he previously owned, were targeted in suspected arson attacks in London between May 8 and 12.
Counter-terror officers arrested a 26-year-old man at Luton Airport yesterday just before 2pm, on suspicion of conspiracy to commit arson with intent to endanger life.
He was taken into police custody in London - where he can now be detained by the Metropolitan Police for an additional 36 hours, for further questioning.
The move comes after a warrant of further detention was obtained at Westminster Magistrates' Court today.
