Mr Raphael said groups of anti-government protesters approached a prison in the capital Maputo on Wednesday. According to him, the prisoners used the disorder to destroy the wall and escape.
Mozambique has been rocked by unrest since disputed elections in October. Official results showed that the presidential candidate from the ruling Frelim party, Daniel Chapo, won.
New protests erupted on Monday when the constitutional court ruled that Chapo had won the election, revising his margin of victory downwards.
The first results in October said that Daniel Chapa had won 71% of the vote against 20% for his main rival, Venancio Mondlan. The court now ruled that he won 65% compared to Mundlein’s 24%.
A A BBC correspondent has been found Maputo looked like a ghost town on Christmas Eve, with almost all businesses closed and people staying at home to avoid the city’s worst riots since Frelimo first came to power in 1975.
Frelimo offices, police stations, banks and factories were looted, vandalized and set on fire across the country. At least 21 people have died in the unrest since Monday, the interior minister said late Tuesday.
Mundlein, who has since fled Mozambique, called on his supporters to demonstrate against what he called a rigged vote.
He said on social media over the weekend that there could be a “new popular uprising” if the result is not overturned.
About 150 people died during the three months of post-election protests.
