The family members of a U.S. citizen who was taken into custody by federal agents in downtown Los Angeles on Tuesday are demanding answers as she was detained while on her way to work.

Andrea Velez, a Cal Poly Pomona grad working in merchandising at a shoe company, had just been dropped off by her mother and sister for the workday when they saw her being taken into custody, adding they had barely even driven a block before the arrest began.

“They didn’t have vests that said ICE or anything,” said Velez’s sister Estrella Rosas. “Their cars didn’t have license plates.”
