The finance minister, Souleiman Seidi, and the secretary of state for the treasury, Antonio Monteiro, had been detained amid investigations into the alleged irregular withdrawal of $10m (£8m) of state funds.
They were questioned on Thursday afternoon by an anti-corruption inquiry to clarify the payments to 11 companies.
In a parliamentary session on Monday, the leader of the country’s main opposition party alleged that the owners of the companies were close to leaders of the country’s governing coalition.
Mr Seidi defended the payments as legal.
On Thursday after the questioning, Mr Seidi and Mr Monteiro were arrested and detained so as not to jeopardise the investigations, local media said.
National Guard soldiers later in the evening invaded the police cells, located near Bandim market, “with AK-47 weapons and bazookas” and extricated the detained officials, the privately owned O Democrata news outlet reported.
