Fourth Iranian arrested in London by counter-terrorism police
Searches have also been carried out at properties in north-west London
A 31-year-old Iranian man has been arrested by Counter Terrorism police in north-west London under the National Security Act 2023.
He was detained on Friday morning and searches were carried out at two addresses in the area.
It comes after another three Iranian men were detained in London on Saturday as part of the same investigation conducted by the Met's counter-terrorism command.
Those three men, aged 39, 44, and 55 can now be detained until Saturday May 17, the force said.
The Met police say the arrests are not linked to a second Counter Terrorism operation, which also took place on Saturday, in which four Iranian men were detained across locations in England on suspicion of preparing an act of terrorism, with a fifth detained under the Police and Criminal Evidence Act.
Reports suggested that the alleged target of the plot was the Israeli embassy in London.
