A small group of demonstrators gathered in the Tunisian capital, Tunis, on Thursday, demanding the release of hundreds arrested in anti-government protests.
More than 200 people have been arrested across Tunisia during a second night of protests, a government spokesperson has said.
The protests have been raging across Tunisia since Monday over the new budget plan introduced by the Tunisian government on January 1, which includes a rise in fuel prices and tax hikes.
Police have insisted they did not kill the man and said he suffered from "respiratory problems". They also want to see better welfare for Tunisia's struggling families.
"Among the achievements of democracy is the opportunity to demonstrate, but we also have an obligation to work for a healthy Tunisian economy", he told AFP.
Tunisia has been praised for its democratic transition following the 2011 revolution that ousted authoritarian President Zine El Abidine Ben Ali and sparked the Arab Spring in North Africa and the Middle East.
Rejecting that accusation, Tunisia's main opposition bloc, the Popular Front, called for a major protest in Tunis on Sunday to coincide with the seventh anniversary of Ben Ali's fall.
But Prime Minister Chahed says this will be the last bad year for Tunisians.
The dashing statement came after a long night of protests against austerity measures hit Tunisian streets.
Despite the escalating situation, government sources denied adopting a decision to impose a curfew at night, but did not rule it out in the event of continued night protests, theft, looting and vandalism, which have targeted a number of public and private facilities. "Yesterday protesters burned down two police stations, they looted shops, banks and damaged property in many cities", Interior Ministry spokesman Chibani said.
After the movement, however, nine administrations during the last seven years in Tunisia have failed to mitigate the plaguing high unemployment rates and economic distress of the common man.
A year ago, the government agreed to a four-year loan programme with the International Monetary Fund worth about $2.8bn in return for economic reforms.
Two Molotov cocktails have been thrown at a synagogue on the Tunisian island of Djerba, setting fire to the building.
Meanwhile, similar protests have broken out in the African nation of Sudan against the autocratic regime of Omar al-Bashir, which announced sharp price increases for flour, resulting in a doubling of the price of bread overnight.
