(BBC) A 50-year-old man has been arrested on suspicion of funding terrorism.
Officers from the Met’s Counter Terrorism Command detained him in Wales and then transferred him to London.
His arrest relates to suspected terrorist financing and money laundering believed to be connected to art collector and diamond dealer Nazem Ahmad, the Met said.
Mr Ahmad is suspected of being a funding source for Hezbollah, a proscribed terrorist group.
Hezbollah is a Lebanese militant group, backed by Iran, which the UK government classified as a terrorist organisation in 2019.
