Lawmakers and schools have rallied against the arrests of students who showed up for court hearings and ICE check-in appointments

A public high school student from The Bronx who was arrested during an immigration court appearance has been released from federal custody after nearly 10 months inside a Pennsylvania detention center.

The arrest of Dylan Lopez Contreras, considered to be the first New York City public school student detained by Immigration and Customs Enforcement, previewed the Trump administration’s new tactic of arresting immigrants inside courthouses as they left their hearings.

“Very soon, my son will be back with his siblings and me — it is both a relief and a blessing,” his mother Raiza Contreras said in a statement through the New York Legal Assistance Group.

Contreras — who was 20 years old when he was arrested and turned 21 while in detention — was enrolled at Ellis Preparatory Academy in The Bronx, which supports immigrant students considered too old to start at a traditional high school.
