Zeneyda Barrera, 18, was arrested at her home in Lynn Monday morning after a neighbor heard a commotion. Barrera is accused of pushing her 12-year-old brother during an argument over a cellphone, according to a Lynn Police Department report.

"It's shocking to me," immigration lawyer Randy Feldman said. "It's unusual that federal immigration resources would be expended for a case like this."

A Lynn teenager sits in a jailhouse on Wednesday with her future in the U.S. in doubt after federal immigration authorities apprehended her at a Massachusetts courthouse where she faced a single misdemeanor charge. Her charge: pushing her brother during an argument over a cell phone.
