After it emerged on Monday afternoon that the Metropolitan Police were probing a fire that had broken out at Sir Keir Starmer’s family home in Tufnell Park in London, a 21-year-old man was arrested this morning on suspicion of arson with intent to endanger life.

The London Fire Brigade and the police had attended the property shortly after 1.30 a.m. after receiving notice of the fire. While the door to the four-bedroom home owned by the Prime Minister was damaged, no one was hurt.

Later in the evening it emerged that counterterrorism officers were also investigating a blaze at a second property linked to Starmer as well as a vehicle fire. The vehicle fire occurred just before 3 a.m. last Thursday. It was on the same street as Starmer’s home.

In a statement, the Met police said: ‘On Monday 12 May at 01:35hrs, police were alerted by the London Fire Brigade to reports of a fire at a residential address in north London. Officers attended the scene. Damage was caused to the property’s entrance, nobody was hurt. The fire is being investigated and cordons remain in place while enquiries continue.’

The force later added:

‘The investigation team are also considering two other incidents – a vehicle fire in NW5 on 8 May and a fire at the entrance of a property in N7 on 11 May – and are investigating whether they may be linked to the fire in NW5 on 12 May.’
