A US judge has ordered the release of a five-year-old boy and his father from an immigration detention centre in Texas, condemning it as driven by a perfidious lust for unbridled power.


The detention of Liam Conejo Ramos, photographed wearing a blue bunny-shaped hat and a Spider-Man backpack, sparked national outcry after he was taken into custody on the driveway of his home in Minneapolis.


The child's father, Adrian Alexander Conejo Arias, was also detained. Following the outrage over the pre-schooler's detention, immigration officials said they did not target a child but were conducting an operation against his father, an illegal alien who abandoned his son when approached.


On Saturday, US District Judge Fred Biery granted an emergency request from the family's lawyer, ordering government officials to release the father and son by 3 February.


The judge also included a photo of Ramos in his fluffy blue hat in his ruling.


The case has its genesis in the ill-conceived and incompetently implemented government pursuit of daily deportation quotas, apparently even if it requires traumatising children, Biery wrote in his ruling.


Biery, an appointee of former US President Bill Clinton, emphasized the need for a more orderly and humane immigration process. He noted, Observing human behaviour confirms that for some among us, the perfidious lust for unbridled power and the imposition of cruelty in its quest know no bounds and are bereft of human decency.


The BBC has contacted the Department of Homeland Security for comment.


Marc Prokosch, a lawyer representing the family, stated the boy and his father were being held at the detention centre in San Antonio, Texas.


Prokosch added that Ramos and his father had arrived in the US in 2024 from Ecuador seeking asylum and had been following the proper immigration protocols.


In recent weeks, US President Donald Trump has escalated immigration enforcement efforts in Minneapolis under an initiative called 'Operation Metro Surge'. Following national criticism, Trump officials suggested that they may begin to withdraw federal forces in the state after recent incidents involving federal agents.


In a separate ruling, a federal judge denied a state government's request to block the Trump administration's deployment of thousands of immigration agents in Minneapolis, stating the state had not proven the activity was unlawful.
