MEMPHIS, Tenn. - It's been almost three weeks since 18-year-old Yasser Lopez was detained by ICE agents on the way to a soccer game.Lopez, a student at Memphis Business Academy, was a passenger in a car that was pulled over by Memphis Police officers, according to his attorney."The circumstances surrounding his arrest, or his detention, I should really describe it as, are particularly egregious," said attorney Jay Fearnley.He pointed out that the other students in the car were all under the age of 18, and their parents were allowed to pick them up.He said Lopez was held and questioned. "MPD felt like there was probable cause to ask him about his legal status, which then prompted them to call ICE and ask him if he had any travel documents or any document that gives him permission to be lawfully present in the United States, and he doesn't have that evidence on him," Fearnley said.In the days following his detainment, classmates at Memphis Business Academy held a walk out in protest.Fearnley said he's also filed to have a federal hearing to question why Lopez was taken into custody. He said he's spoken to Lopez multiple times over the phone since his detention."I think he's certainly disappointed and confused and scared," said Fearnley. He added, "We have a kid who's just turned 18. He came here under the leadership of his mother; you know, a 14-year-old isn't going to tell his mother, "No, I don't want to go with you."He said Lopez, a junior in high school, is being held at the West Tennessee Detention Facility in Mason.He said the teen continues to remain optimistic, although the process is moving slower than expected."If we could get him out of detention, his intent would be to, you know, continue to attend high school, to continue to pursue his education, and to continue to pursue his asylum case and, hopefully, achieve status. Once he achieves status, maybe he could get a scholarship to play soccer at a university," said Fearnley.Fearnley is encouraging people to have their proper documentation at all times as the Memphis Safe Task Force operations continue. He's also encouraging parents to look into the Special Immigrant Juveniles classification process for their children under 18 who do not have citizenship.
