Venezuelan opposition leader Maria Corina Machado was freed Thursday after a brief detention, her Vente Venezuela movement announced on social media.

Machado was detained after an anti-government march in Caracas, her first public appearance in months, amid gunfire, the movement said, adding that she was forced to make several videos during her detention.

Earlier, her ally, former presidential candidate Edmundo Gonzalez, demanded her immediate release as government officials, including Interior Minister Diosdado Cabello, said her arrest was “a fabrication, a lie.”

Vente Venezuela said that Machado was “violently intercepted” in eastern Caracas, and that shots were fired at the motorcycle caravan in which she was riding.

The opposition is protesting across the country in an eleventh-hour attempt to pressure Maduro.

Both the opposition and the ruling party claim that they won last year’s presidential elections.

State election bodies and the supreme court say Maduro, whose time in power has been marked by a deep economic and social crisis, won the July election, although they have never released detailed results.

The government, which has accused the opposition of fomenting fascist plots against it, said it would arrest Gonzalez if he returned to the country and detained prominent opposition members and activists ahead of the inauguration.

Gonzalez (75) toured America this week and met with US President Joe Biden and President-elect Donald Trump’s national security adviser.

The White House and the US State Department did not immediately respond to requests for comment on reports of Machado’s arrest.

‘Tomorrow he will finally be buried’: Machado

Venezuela’s information ministry did not immediately respond to questions about Machado’s whereabouts, while the attorney general said in a message to Reuters that he would not comment.

“Whatever they do, tomorrow they will finally be buried,” Machado said during the protest. “Let no one doubt, what they do tomorrow marks the end of the regime.”

Machado’s appearance marked her first public appearance since August when she went into hiding at an undisclosed location.

Machado, 57, urged protesters to peacefully flood the streets and repeatedly asked members of the police and military – who guarded polling stations during the election – to support Gonzalez’s victory.

“I’m not afraid, I lost my fear a long time ago,” said 70-year-old Neglis Payares, a retired central bank worker, as she gathered with other opposition supporters in western Caracas in the morning.

Reuters witnesses estimate that around 7,000 people gathered in Caracas around 2:20 p.m. local time. In the days after the election, thousands also took to the streets.

Maduro, 62, has been in power since 2013. He has the vocal support of leaders in the armed forces and intelligence services, which are run by close allies of powerful Interior Minister Diosdado Cabello.

Security forces set up checkpoints across the country.

Gonzalez has repeatedly promised to return to Venezuela, but has not given details on how. A warrant was issued for his arrest for alleged conspiracy, prompting his escape to Spain in September.

Machado is being investigated by the state attorney

Machado is under investigation by the attorney general in at least two cases, but no warrants have been released for her.

The government detained several high-profile politicians and activists, including a former presidential candidate. This week, the attorney general’s office said it had freed more than 1,500 of the 2,000 people, including teenagers, detained during the post-election protests.

Venezuelans living abroad also held protests, including in Madrid, where Gonzalez’s daughter Carolina Gonzalez spoke to hundreds of protesters.

“My dad sends a hug to all of you, kudos to the brave people of Venezuela,” she said, her voice breaking.
