A suspected Basque terrorist was arrested today in London.
Spanish national Kemen Uranga Artola, 43, was arrested by officers from the Metropolitan Police's extradition unit.
They executed a European arrest warrant alleging his involvement in terrorism-related offences in Spain.
Artola, who featured on a 2002 American government's list of terrorists, was arrested in the NW5 area and will appear this afternoon at Westminster Magistrates' Court for an extradition hearing.
His arrest is unrelated to the Olympics, Scotland Yard stressed.
More than 20 suspected Eta members have been arrested across Europe after the terrorist group announced an end to violence last October.
The last suspect taken into custody was Inaki Imaz in France on Monday.
The latest arrest was made after detectives liaised with Spain's Comisaria General del Informacion de la Policia Nacional.
It is believed Uranga Artola used false documents while living in London.
