An 8-year-old Haitian boy who lost Temporary Protected Status earlier this year was taken into federal custody after an immigration check-in, according to local advocates and school officials.

The third grader, who attends Fay Elementary School in San Diego, was placed into government custody alone after attending an Immigration and Customs Enforcement appointment with his uncle on Thursday, according to his school district and an advocacy group.

"The eight-year-old received a letter to meet with an ICE agent," the San Diego Unified School District said in a letter to DHS.
