Imprisoned Bishop Rolando Alvarez of Nicaragua is Reported to be in Solitary Confinement in a Cell known as "El Infernillo"

The Catholic Bishop Rolando Alvarez, who was sentenced to 26 years in prison in Nicaragua last week, is reported to be in solitary confinement in the "La Modelo" prison: This is indicated by a report by the news outlet "Despacho 505", which relies on anonymous church sources and people in the detention center. It was said that ruler Daniel Ortega himself decreed that the Bishop of Matagalpa had no contact with other political prisoners. The bishop was convicted to 26 years in prison on February 11th.
The bishop is being held in cell 300, known as "El Infernillo" (the little hell), at the prison in the town of Tipitapa, near Managua, the report said.

Bishop Alvarez has openly denounced human rights violations and the prevailing conditions in Nicaragua in the past. In a speech on February 9, ruler Ortega expressed his hatred of Alvarez. The president claimed that the bishop had refused to obey government orders. Barely 24 hours after his speech, the Sandinista judiciary sentenced the Bishop of Matagalpa to four counts of 26 years and four months in prison, a fine and the loss of his civil rights.

US and European bishops call for release
Immediately prior to his sentencing, Bishop Alvarez declined an offer to leave the country with 222 other political prisoners. On behalf of the United States, which took in the dissidents and issued them humanitarian visas. State Department spokesman Ned Price on Tuesday condemned Nicaragua's actions and again called for "the immediate release of Bishop Alvarez" and all political prisoners who are being held solely for the purpose they had exercised their rights. The spokesman welcomed Pope Francis' "decisive support" for the imprisoned bishop - he had expressed his solidarity on Sunday.

In the meantime, the repression against the Catholic Church, which in Nicaragua is considered the most important voice against the Ortega regime after the arrest of all opposition leaders, continues. "Despacho 505" reported on Tuesday (local time) about a police raid on another high priest in the village of Monimbo and about intimidation against several pastors in the villages of Telpaneca, Madriz and Ciudad Antigua. Some of the clergy were also temporarily imprisoned and later released under threat of punishment, it said.

In addition to numerous local churches worldwide, the chairman of the Council of European Bishops' Conferences (CCEE), Archbishop Gintaras Grusas, released a statment:

Remarks from the CCEE President on the situation in Nicaragua

The situation that the Church in Nicaragua is experiencing is a source of pain and concern. On 11 February, Bishop Rolando Álvarez of Matagalpa was sentenced to 26 years in prison and lost Nicaraguan citizenship. In the previous days, four Catholic priests, two seminarians and a deacon from the diocese of Matagalpa, arrested together with the bishop, had been sentenced to ten years.

On behalf of the Presidents of the European Bishops’ Conferences, meeting in assembly, the CCEE President, Gintaras Grušas, expresses the sympathy and solidarity of the European episcopate to the citizens and to the Catholic Church of Nicaragua. He considers this condemnation to be a serious wound both to relations between the Church and the government of the country, and to the rule of law.

In fact, since his arrest in August 2022, it has been unclear what the charges against Bishop Álvarez were, other than the official ones of “false information” and “treason”. It was impossible to follow the trial in detail and to understand how the charges were supported and proven. We only heard regarding the conviction. A conviction, it was learnt, that would not have been forthcoming if the bishop had instead agreed to leave the country with more than 200 political prisoners who travelled in recent days to the United States.

The Church has never wanted anything other than to contribute to the welfare of the country in which it serves. Even in times of greatest persecution, the Church has supported the weakest, consoled the suffering and given refuge. It is doing so also in Nicaragua.

The President of the Council of European Bishops’ Conferences calls on all brother bishops to make their governments aware of the serious violation of the rule of law that is taking place in Nicaragua. At the same time, he calls on the Nicaraguan authorities to listen to the voice of the people and to take decisions that favour a peaceful transition in a country that has been experiencing social conflict for five years now. He calls for the release of political prisoners as a sign of goodwill to restore a dialogue that can lead to a just social peace, and which will allow the country to prosper.

The Churches throughout Europe embrace the Church in Nicaragua, Bishop Álvarez and the priests currently imprisoned, renewing their affection and support and, accepting the call of Pope Francis to pray “for them and for all those who suffer in that dear nation”, asking the Lord “to open the hearts of political leaders and all citizens to the sincere search for peace that comes from truth, justice, freedom and love”.
