A judge ruled Wednesday that the Trump administration must facilitate the return of a 20-year-old migrant, who was deported last month, because his removal violated a class action lawsuit settled last year.

Neiyerver Adrian Leon Rengel faced the same fate as hundreds of other Venezuelans men who have been deported to El Salvador based solely on tattoos the U.S. government claims indicate affiliation with the Tren de Aragua gang, even though experts say that, unlike Central American gangs, TdA does not typically use tattoos to identify its members.

Relatives of many deported Venezuelans and their lawyers have denied that they are Tren de Aragua members and have said they were never given the chance to contest the Trump administration's allegations of gang affiliation.
