A Dutch woman has been arrested in the Netherlands in relation to the shooting of a Spanish former politician in Madrid last year. Alejo Vidal-Quadras, a founder of Spain’s far-right Vox party, was shot in the face near his home in the wealthy Salamanca neighbourhood on 9 November by a motorcycle passenger. A long-time supporter of the Iranian opposition, Vidal-Quadras, 78, has accused the Iranian regime of involvement in the shooting. Four people had already been arrested as part of the investigation into the shooting, but the suspected gunman – a French national of Tunisian origin with several previous convictions in France – remains at large. “A woman was arrested in Holland for her alleged participation in the financing and preparation of the attack on Vidal-Quadras,” the national police said in a brief statement on Tuesday. Police said she was detained after Spain issued a European arrest warrant. Vidal-Quadras was a member and then vice-president of the European parliament between 1994 and 2014. He was also a former head of the centre-right People’s party in Catalonia.
