PA MediaTwo men have been arrested on suspicion of arson with intent to endanger life after four Jewish charity-owned ambulances were set on fire in north London, the Metropolitan Police has said.
Four Hatzola ambulances were set ablaze in Golders Green, London, in the early hours of Monday, leading to an investigation led by the Met's counter-terror officers.
One man, 47, was arrested in north-west London and a second, aged 45, was arrested in central London on Wednesday morning.
Officers are carrying out searches at the two addresses.
Commander Helen Flanagan, head of counter terrorism policing London, described the arrests as an "important breakthrough" but said the force was aware of CCTV footage which "suggests there were at least three people involved".
"We fully recognise the local community will still be concerned and our investigation very much remains active and we will continue to work to identify and seek to arrest all of those who may have been involved," she added.
Detective Chief Superintendent Luke Williams outlined additional security measures which have been put in place, which include police officers being deployed to protect certain locations, alongside "additional highly visible armed police patrols".
He added that these measures are precautionary and not in response to any specific threat.
Four replacement ambulances, provided by the government, arrived at Hatzola on Tuesday.
