New rallies have been held across Peru against the decision to pardon former President Alberto Fujimori.
In the capital Lima, students, trade unionists and human rights activists marched amid a heavy police presence.
The protesters were demanding not only the quashing of the pardon but also the resignation of President Pablo Kuczynski, who granted it.
Fujimori, who was serving 25 years for human rights abuses and corruption, was pardoned on Christmas Eve.
This is the fourth time thousands of Peruvians marched to show their contempt for what they said was political collusion at the top.
Kuczynski pardoned Fujimori, 79, just three days after a group of lawmakers - lead by Mr Fujimori's son Keiji - helped the president avoid an impeachment process.
The threat of impeachment stemmed from accusations the president had been receiving money from Brazilian firm Odebrecht in exchange for contracts, a claim he denies.
Kuczynski also denies striking a deal with the Fujimoris.
