Arias Sánchez has a fourth accuser

Eleonora Antillón had kept her secret bottled up for more than 30 years.

But when she read an article on social media Tuesday saying a woman had accused ”scar Arias Sánchez, the former president of Costa Rica, of sexual assault, she did not hesitate: “From personal experience with him,” she wrote on the social media platform, “I BELIEVE her!!”

Antillón is among four women in a 48-hour period to accuse Arias, 78, of unprovoked and unwanted touching or sexual assault.

The allegations are a serious blow to the legacy of Arias, who won the Nobel Prize in 1987 for his effort to bring peace to Central America. Twice president of Costa Rica, he has been one of Latin America’s most respected figures.

Antillón, a former talk show host known by her nickname, Nono, said that Arias sexually assaulted her in 1986, when he was a presidential candidate and she was a press aide.

Two former journalists and a book editor came forward after The New York Times and Seminario Universidad published accounts by a psychiatrist at a state hospital in San José, Costa Rica, who filed a formal criminal complaint saying that four years ago, Arias forced his fingers inside her.

“People end up thinking, ‘If she dared, others will dare,’” Antillón said. “I want to unmask the impostor politician.”

Prosecutors opened an investigation Tuesday after the psychiatrist, Alexandra Arce von Herold, 34, gave a formal statement, saying Arias had sexually accosted her in his home office.

Antillón said in one of their earliest meetings, Arias put his hands on her leg. Another time, he put her hand on his erect penis. When she resisted, he pushed her against a wardrobe and kissed her, she said. She clenched her mouth shut, and he licked her face, Antillón said.
