OAKLAND (CBS SF) — BART fought back Thursday against previously reported claims that it has been sharing information with federal immigration agents.

In a statement, the BART police chief denied the allegations, stating that the information, which was inadvertently sent to the Northern California Regional Intelligence Center (NCRIC), was not shared with ICE.
