Vidal-Quadras accused Iran of being being the attack
A police source told The Olive Press: “When entering the license plate into the system, all the alarms went off.”
It became the scene of an investigation on Monday evening involving more than 20 uniformed officers.
The Technician Specialist in Deactivation of Explosive Artefacts (Tedax) bomb squad and sniffer dogs were also involved in the raid, before agents were seen taking away multiple suitcases and boxes as evidence.
A third individual, a man, was also arrested yesterday, in Fuengirola on the Costa del Sol. Neither of the three are believed to have fired the shot that almost killed Vidal-Quadras.
Reuters reports that Vidal-Quadras accused Iran on Wednesday of being behind his attempted murder.
Vidal-Quadras did not offer any proof to back up his claim and Spanish authorities have not confirmed any such theory.
Iran's embassy in Madrid said in a statement it "firmly condemns any kind of terrorist operation," though it did not immediately comment on Vidal-Quadras' claims.
The three were being transferred to Madrid on Wednesday to appear before an investigating High Court judge.
