Police have arrested a second man in connection with three arson attacks targeting the Prime Minister.

The 26-year-old was arrested around 1.45pm on Saturday at London Luton Airport on suspicion of conspiracy to commit arson with intent to endanger life.

The arrest was made by counter terrorism officers from the Eastern Region Special Operations Unit. The man has been taken into police custody in London.

The arrest relates to three incidents - a vehicle fire in NW5 on 8 May, a fire at the entrance of a property in N7 on 11 May and a fire at a residential address in NW5 in the early hours of 12 May.

Today's arrest follows the arrest of 21-year-old Roman Lavrynovych, of Sydenham, on Thursday, who appeared in court yesterday charged with three counts of arson with intent to endanger life.
