An Iranian man, 31, has been arrested in North London as part of a counter-terrorism policing investigation. It comes after the Metropolitan Police arrested three Iranian men last Saturday as part of the same investigation.

The latest suspect was arrested on Friday while police searched two addresses in the area. The force said the other suspects, aged 39, 44 and 55 could now be detained until Saturday, May 17.

Meanwhile, four other Iranian men were arrested in a separate police operation last Saturday. They were detained across England on suspicion of preparing an act of terrorism.

It's reported the suspects were plotting an attack on the Israeli embassy in London. A fifth man was detained under the Police and Criminal Evidence Act.

The Met Police said: "A fourth man has been arrested in London as part of a Counter Terrorism Policing investigation.

"A 31-year-old man [D] was arrested at an address in north-west London this morning (Friday, 9 May) as part of the investigation, which is being led by the Met's Counter Terrorism Command."

"The man, who is an Iranian national, was arrested and detained under section 27 of the National Security Act 2023."

The force added: "Three men, aged 39 [A], 44 [B] and 55 [C], were arrested on Saturday, 3 May as part of the investigation. Warrants of further detention have been sought and obtained for them today, meaning the three men [A – C] can be detained until Saturday, 17 May.

"As part of this investigation, searches were also carried out at two addresses in north-west London, on Friday, 9 May. The searches are now complete.
