In a note sent to the media, the MAI confirmed the searches, saying that all the collaboration is being provided in carrying out the investigation.

Several media outlets are broadcasting these searches, indicating that they are related to the dossier of anti-smoke masks of the "Aldeia Segura" programme and that there are suspicions of crimes of economic participation in business and diversion of subsidy.

The anti-smoking mask case led the ministry to open an investigation in July into the hiring of fire awareness material.

Two days after the minister's decision, the deputy secretary of state for civil protection resigned after he was informed of his involvement in choosing the companies that produced the emergency kits containing the anti-smoke masks for the "Aldeia Segura" programme.
