A flooring contractor from Brooklyn, New York, received news he had dreamed of for more than a year when a Bolivian judge released him on bail Tuesday.

Jacob Ostreicher wore a white bulletproof vest as he spoke with reporters after the hearing.

Supporters of the businessman, 53, who had been imprisoned for 18 months, say he faces death threats for exposing Bolivian government corruption connected with the case against him.

"His life remains at risk every day that he remains in Bolivia," U.S. Rep. Chris Smith, R-New Jersey, said in a statement Tuesday.

Ostreicher was arrested in June 2011 on suspicion of money laundering tied to a rice-growing operation.

He has denied the accusations and has claimed for months that corrupt officials had trumped up the case.

Bolivian authorities arrested six government officials last month, accusing them of trying to extort and steal from Ostreicher.

Now some of his one-time accusers -- including former employees of the attorney general's office and the country's interior ministry -- are behind bars in the same prison where he was held.

Bolivia's state-run ABI news agency has described that facility -- the Palmasola prison in Santa Cruz, Bolivia -- as the country's "most dangerous and overcrowded."

On Tuesday, Ostreicher was released on bail of 100,000 bolivianos (about $14,200), and now will be in more comfortable conditions, although the case against him hasn't been dropped.

He will remain under house arrest from 10 p.m. to 6 a.m., Judge Eneas Gentile ruled Tuesday, but can move freely at other times.

Smith and U.S. Rep. Nydia Velazquez, D-New York, praised Ostreicher's release as the "first positive development" in the case.

"But this is only the beginning of the end," Smith said. "Jacob has incurred permanent damage to his health and has lost over 18 precious months of his life with his wife, children and grandchildren."

After the hearing, an ambulance transported Ostreicher to a clinic where he is being treated for Parkinson's disease, ABI reported.

In an interview with CNN en Español from a hospital bed earlier this month, Ostreicher said he was wearing a bulletproof vest out of fear for his safety, even as officials had been arrested in the corruption probe connected with his case.

"Actually I feel much less safe. That's why you see me sleeping with this bulletproof vest," he said. "Because now there are some officials in prison."

The detention of Ostreicher, who at one point went on a hunger strike to protest his imprisonment, drew international attention. Actor Sean Penn sat at his side last week, calling for his release.

Speaking to reporters Tuesday, Ostreicher said his case was only one of many in the South American country.

"I want Bolivia to know that not only my family and I have been victims of these extortioners who are detained today. Also hundreds of Bolivian families have been victims, and the greatest victim has been President Evo Morales, for which these people deserve to be punished with the harshest penalties that exist," he said, according to ABI.

Demonstrators outside the courthouse Tuesday both advocated and denounced Ostreicher, CNN affiliate Bolivision reported.
