An Afghan asylum seeker died in Immigration and Customs Enforcement custody in Texas over the weekend, less than 24 hours after being detained by federal agents, according to an advocacy group.

Mohammad Nazeer Paktyawal, 41, was arrested Friday morning outside his apartment in a Dallas suburb while taking his children to school, according to AfghanEvac, a military veteran-led advocacy organization. He died on Saturday while in ICE custody.

Paktyawal had previously worked with the United States military in Afghanistan and was living with his wife and six children while his asylum case remained pending, the group said in a statement released Sunday.

Shawn VanDiver, president of AfghanEvac, provided details about the circumstances of Paktyawal's arrest and death. The organization advocates for Afghan nationals who assisted U.S. military operations.

ICE has not immediately responded to requests for comment regarding the death or the circumstances surrounding Paktyawal's detention. The cause of death has not been disclosed.

The incident highlights ongoing concerns about conditions and procedures within the immigration detention system, particularly for asylum seekers who previously assisted U.S. military operations abroad.
