It happened when Lorena Yanez-Mata walked into the Time Warner Cable office in Burlington to sign up for cable service.
The documents she turned in to Time Warner showed that she was undocumented.
Time Warner Cable said an off-duty officer, who was working security for the company, got the documents and gave them to police.
Time Warner put out this statement: "It is not our policy to share this kind of information with law enforcement and this action was not following any Time Warner Cable procedure or direction. TWC did not refer Ms. Yanez-Mata to either to the county prosecutor or Homeland Security and did not request prosecution."
The statement did little to comfort Yanez-Mata's friends and advocates.
"I understand if that's the company policy but obviously their representatives on the ground are not listening to what the company is saying because it's still their fault that Lorena is currently in deportation hearings," said Moises Serano , with NC Dream.
Yanez-Mata has a deportation hearing Thursday where a judge will decide if she will be sent home. She has an 8-year-old daughter.
