The prisoner is accused of the crimes of illegitimate access to an information system and hacking through an information system, computer fraud, criminal association and embezzlement.
The Criminal Investigation Service (SIC) said that investigations into this complex process continue to fully clarify this fraudulent scheme that has already led to the arrest of several employees of the General Tax Authority (AGT).
The arrest was announced a day after the director of the Value Added Tax (VAT) department at AGT was also arrested due to "strong indications" of his involvement in the fraudulent scheme of compensation payments, in relation to VAT refunds.
The AGT team will respond to suspicions of crimes of illegitimate access to information systems and breaches through information systems, computer fraud, criminal association and embezzlement.
The Ministry of Finance has announced, however, that it will order "an audit of the systems, processes and procedures in use at the General Tax Administration (AGT)", in the context of the scandal over fraudulent VAT refunds.
The investigation is into a fraudulent Value Added Tax refund scheme, which is believed to have cost the public treasury at least seven billion kwanzas (7.3 million euros) involving tax administration officials.
The SIC highlights that the scheme was constructed by tax officials from different areas and functions, who took advantage of these privileges to carry out "several fraudulent deals".
