The mother of a baby who was rescued in Concord from an exposure to fentanyl last week has been charged with felony child abuse, authorities said Friday.

Brittany Danielle Hicks, 31, whose listed address is in Hayward, faces one count. Authorities say she tracked down a Concord police officer on the night of March 26, because her 2-year-old child stopped breathing.

Her arraignment was scheduled for Friday afternoon.

Concord police Officer Aaron Khamosh rescued the toddler after administering Narcan, a drug used to offset Opioid overdoses. Authorities said that when Khamosh was rescuing the child, Hicks admitted to him the child’s exposure to the fentanyl.

According to the charging documents, authorities believe Hicks willfully allowed her child to be in a position where should could be exposed and harmed by the drug.

Authorities said Hicks frantically waved down Khamosh while he was on Salvio Street patrolling. Khamosh administered two doses of Narcan, and the baby regained consciousness. Paramedics continued the CPR that Khamosh also started, and the child went to UCSF Benioff Children’s Hospital in Oakland.
